Thanks for all your help, I'll probably wait until after the Sony is launched, to see if there are any problems with it.
I'm not very computor savy so it would have to be easy for me to d/l my word docs and web pages onto it. I don't invisage buying many actual 'ebooks'.
I would use it mainly for reading d/l'd web pages and word docs. I was also looking at the 'ASUS eee', as an alternative pocket size pc. That seems to have web & program possibilities, but of course the screen wont be half as good. Also it's probably heavier & bulkier.
I'm trying to work out the best possible combination for an avid reader on the move to not have too many 'gadgets' to lug around!
