Hi MaggieP!
Your devices "talk" to one another, so when you've bought a book, it's downloaded to your Kindle and to your Kindle app (obviously needs to be installed!) on your iPad, iPod etc. which I do find useful. And, say you've been reading something on the Kindle; when you open the same book on the iPad it will ask you if you want to sync to the last page you were reading on the Kindle...very clever gizmos!
My little Kindle is 3G and Wi Fi, light as a feather and, as I've said before, saves me overweighting my luggage allowances with my body weight in books! So enjoy it.

Am a bit of a nitwit technically (my computer, later laptop, has been used mainly for word-processing) and having read all the erudite messages about Kindle, am now more terrified than ever to buy one! Do you need anything else to link it to, or can it be used independently?? Also do not want to find myself paying about £20 to download a book, or only be able to access authors I've never heard of. But getting to the Library gets more painful by the day.

there will be no stopping you now.
