Thanks everyone. Those are some very useful comments you got there. I have been to US before but I will be traveling to 4/5 states in two and half week so delivering ahead is a little troublesome. But I probably would be able to manage by delivering to my final destination. But I really wanted to use the device before ordering it.
Pocketbook 602 seems real good but I'm a little unsure if I wanna buy it without seeing. I have checked the matrix and its very helpful but they don't provide much explanation in terms of navigation/collection etc. so I wanted first hand opinion. Anyone has good idea about page turning speed? I used to find the prs300 page turning irritatingly slow. Any of the nook/kobo/kindle/pocketbook that slow? or they are all much faster now?
