Plus’ as covered above, its very good at what it does, even the browser is OK for reading stuff (wikipedia etc) less so for writing as theres no keyboard on the basic version.
Minus, the price of books, the bestsellers were 2x or 3x the price of the paperback in Tesco! I was expecting iTunes levles of pricing with paperbacks that used to be £7-£8 being about a third of that now that theres no printing costs.
Free books are hit-and-miss, just because you can publish your own book for free doesnt mean you nececeraly should, a lot of crap makes it into the thop 100! I can forsee a lot of ‘good’ free books being re-released after being bought by a publisher and gone through the usual proof reading and editing, a bit like a band releasing a demo EP, getting a recod deal then releasing their album.
