The large majority of households will be fed with a domestic water supply which is defined as "hard water". This is just a definition which is applied to signify water which has a fairly high concentration of minerals in it. Magnesium and calcium are the two most important minerals. According to the World Health Organisation, there are no health problems associated with hard water supplies - but it can affect the effective operation and lifespan of a variety of different domestic appliances.

As a consequence of hard water, mineral deposits can be laid down in water pipes and a range of household appliances. Household appliances which use hot or boiling water are especially at risk as heating the water frees the minerals it contains which then solidify as "scale". Coffee makers, kettles, steam irons, dishwashers and washing machines are all prone to this effect - as are household central heating systems and boilers.

The amounts of minerals that are released depend upon a number of different variables. One of these is temperature - the higher the temperature of the water, the more minerals will be released and the more scale will form. Running central heating systems, washing machines and dishwashers at lower temperature settings will reduce the amount of scale deposited and ensure that these appliances operate efficiently and have a long lifetime. Some soaps and detergents contain anti-scaling ingredients and these can also help to minimise scaling.

Using a lower water temperature with appliances such as steam irons, kettles and coffee makers isn't very practical. Some kettles come with filters built in these days, which can prevent or reduce the incursion of harmful minerals (as well as improving the taste of hot drinks). Some modern irons incorporate specially designed, removable scale traps which make it easy to wash away any scale under a running tap. Other alternatives include periodically cleaning your appliances with special anti-scale chemicals.

Whilst there is no danger to health as a result of hard water, some people may dislike the taste it results in for either hot drinks or boiled and steamed food. On the other hand, there are those who swear that hard water makes better tasting tea than soft water. It's a matter of personal taste at the end of the day. If the flavour of your food and drinks isn't satisfactory, you can always use a water filter. These range from very cheap (but effective) jug filters, to under sink or even whole house filters. These are cheaper than you may think and are really quite simple to install.

Whilst it may seem like a bit of an inconvenience, it's well worth taking a little effort to combat the effects of a hard water supply. Apart from improved efficiency of domestic appliances, using the right detergents, operating at a lower water temperature and occasional cleaning will save you money and extend the life of your household goods.

Discover how you can cut your ironing time in half by using a Tefal steam generator iron - it's a lot quicker and the end result is better as well

Amazon seemed to have found the perfect product in their Kindle reader. It was by far the market leader in the e-book reader arena, commanding a 60% share of all sales, and there was no real competition to speak of. Despite the launch of competing e-book readers by other manufacturers such as Bookeen, Barnes and Noble and Sony, there was no genuine competition and the Kindle's top position seemed to be unassailable.

Then the Apple iPad came along and, although it is an entirely different device, it did look set to spoil the party somewhat. The iPad is not without some fairly major flaws of its own, and whilst most Apple devices seem to provoke a "love them or loathe them" response, the numbers of people who would buy almost anything with the Apple logo on it are certainly large enough to make a major dent in the sales of the Kindle.

As well as releasing new, sexy hardware, Apple also struck a deal with many of the major publishers which let them charge whatever they wanted for e-books - as long as they weren't offered for less on any other device - the Kindle in other words. This looked set to put a bit of a spanner in the works of Amazon's policy of providing e-books for $ 9.99 or less. It certainly seems as if the price of e-books has been creeping upwards since the launch of the iPad. It does seem a little strange that increased competition should drive prices upwards - but there you have it.

The price of the e-book readers themselves has fallen however. Barnes and Noble cut the price of their Nook reader to $ 199. Amazon's Kindle 2.0 is now selling for just $ 189 - a huge reduction over the $ 359 launch price of February 2009. The Kindle DX can now be yours for just $ 379, a saving of $ 110 over the previous $ 489 ticket price.

So the top of the range, and freshly updated, DX reader is now over $ 100 cheaper than the entry level Apple iPad - and unlike the iPad it requires no monthly internet connection fee. The iPad is, of course, considerably more than an e-book reader - and many customers will be quite happy to pay more for a more powerful device which can be used for a variety of different applications - even if it does have a considerably shorter battery life.

Time will tell whether or not this downward price trend for e-book readers is no more than a knee-jerk reaction to the appearance of the iPad or whether it is the beginning of a new pricing policy. It may be that companies such as Barnes and Noble and Amazon could use the upward trend in e-book prices to offset lower hardware ticket prices and make their profit on the sale of e-books over the lifetime of the device. In Amazon's case, it may be no more than a holding tactic until the next generation Kindle, complete with color screen, hits the market later this year.

Amazon, using their Kindle reader family as a vehicle, has been a major player in the development of both the e-book reader and e-book market. The first Kindle was released in November of 2007. In February of 2009, the updated and enhanced Kindle 2.0 hit the market, quickly followed by the large format Kindle DX in the summer of the same year.

The Kindle readers dominated the market with a 60% share of all American e-book reader sales. Sony's PRS reader - which was actually available in 2006, some time before the Kindle - followed in second place with a 35% market share. Other companies quickly saw the huge potential of the rapidly developing e-book reader market and either launched or updated their own readers in order to get a share of the available sales.

Companies such as Sony, Barnes and Noble, Bookeen, Plastic Logic and iRex did their best to get their share of the new and fast developing e-book market, but the Kindle's dominance looked to be pretty much unassailable. It wasn't until the launch of the Apple iPad that the Kindle had any credible competition - even although the two devices were very different and would appeal, you would imagine, to different audiences.

Differences in the devices and their intended applications notwithstanding, e-book reader prices have tumbled since the launch of the iPad. You can now pick up the Kindle 2.0 for just $ 189 - a huge reduction over the launch price of $ 359 - and a significant drop from the pre-iPad price of $ 259. The newly upgraded Kindle DX can be yours for just $ 379, down from $ 489. Barnes and Noble's Nook reader is now on sale at just $ 199.

Although the iPad seems to have provoked a round of price cuts among the manufacturers of e-books, the same cannot be said about the price of the e-books to read on these devices. Prior to the launch of the iPad, Apple had negotiated a deal with the major publishing houses which let them set the price of their e-book editions at pretty much whatever they wanted - as long as they did not allow the same e-book to be offered cheaper on any other platform. This was seen as good news by the publishers, who had been unhappy with Amazon's policy of selling all e-books for $ 9.99 or less.

Amazon may have had to abandon their low e-book price policy - but that wasn't necessarily a disaster for them. Considering the way that Amazon have made it possible to read Kindle books on such a wide variety of different devices - you can use the PC, the Mac, the iPod Touch, the iPhone, the iPad, your Blackberry and any device which runs Android to read Kindle books right now (and no doubt there will be further additions in future) - it must be obvious that Amazon are more interested in book sales than hardware sales. The latest downward price movement for e-book readers and simultaneous price increase for e-books means that they can now sell the hardware for less and make their profit by selling e-books over the life of the hardware. The same will apply for Barnes and Noble and Apple themselves of course.

This trend may tend to favor companies which have a foot in both the book and hardware sales camps. Considering the current number of devices which can be used to read Kindle books, it looks as if Amazon will be a major player in the future of digital publishing for some time to come.

Do you use bread machine mixes when you want to make yeast bread in your automated bread-making machine? If you do, why do you? Because it's easier? It is so simple to make gourmet bread quickly from easy-to-follow bread recipes and so much more variable too. If you use bread machine mixes you are limited to the bread machine mixes there are in the shops " no matter how many of them there are there.

On the other hand, a good bread machine recipe book is infinitely more flexible than bread machine mixes. A good bread machine cookbook might give you 150 or so recipes originating from several countries, but it will also inspire you to adapt those recipes, encouraging you to be creative and invent your own style of bread.

Bread machine mixes are really quite restricting and you have no control over what goes into the bread machine mix either: preservatives, colouring, MSG, salt or who knows what. Yes, it says on the label, but you cant take them out, if you limit yourself to bread machine mixes.

Making bread is really quite easy. Or to put it correctly, the ingredients to making bread are really quite simple. To bake a very basic loaf of bread, you only need: flour, water, yeast, sugar, salt and fat or oil. The difficult part about making bread is the mixing. It can take four hours to mix the bread making ingredients together; to wait for it to rise; to knead it; wait for it to prove; knead it again and bake it.

But, if you have a bread making machine you can automate the hard bread mixing, proving, kneading cycle and if you have a bread-making recipe book you will be provided with numerous recipes to guide and inspire you.

What could be more simple? You consult the bread-making machine recipe book for an tasty recipe; you put the everyday ingredients into the bread mixing bowl of the bread machine and you put the yeast into a time-release box on the top of the bread machine; set the timer and just go about your daily life or even go to sleep!

The bread making machine will mix the ingredients and check the timer. My bread-making machine has a sixteen-hour timer. So, if you want your gourmet, yeast bread ready for 6:30 AM, the bread-making machine will mix the flour, water, salt oil and sugar immediately, add the yeast at say, 4 AM, knead, prove and bake the bread and ring a bell at 6:30 to announce that your gourmet food is ready.

Except that you won't need the alarm to let you know that. The aroma of freshly-baked bread will permeate your house and you will be very much aware of the fact that your bread making machine is just about ready to serve one of the best loaves of bread you've ever had in your life! And you will never ever look for bread machine mixes again. You'll be overflowing with ideas for your own bread machine mixes in no time at all and you'll be giving bread away as presents so that you can try out your next very own bread machine mixture.

Bread machine mixes: we don't need 'em?
