I was just reading an article that says it doesn't use a normal WiFi system but rather:
"Downloads are done via Amazon Whispernet, using the EVDO network"
for the article.
I don't know what EVDO is.
Having said that I can understand the idea of having computer manuals and other reference books in this format provided your investment is guaranteed protected - but (and it is a big BUT) the books will be locked to one device - what happens when it dies?
Also I have been stung with eBooks before - what happens when you buy an eBook and need to download it again? As far as I can tell this is supposed to be possible from Amazon but in the past I have been unable to redownload eBooks from Amazon because publishers have withdrawn them from the eBook market.
Given that the library size is limited is there a way to store books on other media (such as a computer hard disk)? It seems to suggest that it doesn't need to interface with computers at all - even to purchase and download books. Does this mean you are relying on Amazon to manage your library within your Amazon account and allow books to be grabbed from your library on the fly?
Finally would anyone choose to read a novel on this sort of device - there is no way I want to lie in bed with a glowing lump of plastic glaring at me instead of a comforting paperback that can happily drop on the floor without problems when I drop off to sleep!
