Kindles

If you have it in a protective case that absorbs the impact, the Kindle should be fine unless you actively throw it. Mine has occasionally slipped onto the bedroom floor, which is carpeted, and has come to no harm.

I have dropped mine on the floor when I have dropped off to sleep and its been fine, but it is in a case.

If you are getting a case go onto Ebay as they are much cheaper than Kindle.

I dropped mine outside on concrete!I miss it when I go away because I had the 3G version and could access emails/ Internet practically anywhere for free.It was quite slow but really useful when you needed to check something and were nowhere near access to WiFi.

I was so anti-kindle but was given one as a present and in the first week I read four books and had difficultly putting it down.
Also agree with glassortwo you can get some really smart cases on ebay.
