Kindle (Wi-Fi) is a great choice if you already have a high-speed internet connection and wireless router setup at home, and do not want the added convenience of a 3G connection which enables you to download books anytime, anywhere on the go. If you do not have Wi-Fi setup in your home, Kindle 3G would be a better option.

Kindle 3G (Free 3G + Wi-Fi) is the easiest option because there is no wireless setup—you are ready to shop, purchase, and read right out of the box. Built-in Free 3G connectivity uses the same wireless signals that cell phones use, but there are no monthly fees or commitments—Amazon pays for Kindle’s 3G wireless connectivity. The added convenience of 3G enables you to download books anytime, anywhere on the go—without having to find a Wi-Fi hotspot connection. With wireless coverage in over 100 countries and territories, Kindle 3G is a great option for travelers.enter link description here Scroll down for more on comparisons.

I should have added that I purchased one for my wife last Christmas - the one that has been regularly advertised on TV at £109 (now £111 I believe) It is the WI-FI version only as she only uses it at home. I haven't seen the new one at £89 but the last link I sent you shows you the differences - ie: the 3G and Wi-Fi has a keyboard - the £89 version has a 5 way controller and not sure but I think it may have on-screen keyboard.

It is an excellent e-book reader and very soothing on the eyes as it is not back-lit and the text is just as if you were reading a real book.

Have a good read of all the features and comparisons. I can thoroughly recommend the Amazon Kindle - who knows, you may be able to do away with that bookcase ! It could be a good Christmas for your husband - I am sure he will be delighted.
