... The first differences which fell to my eyes were a lower screen resolution and a higher weight, for the Pocketbook. And indeed user reviews seem to agree, user zetareticuli saying:
Yes, there's a surely a difference, but the price difference is the one which springs to mind.
But at the very least, this tells us that already in the very first year of color tablets, we are finding products priced under $200, and that is quite amazing. When the iPad came out in early 2010, everybody was shocked that it was priced so low as $500. (Indeed I still consider that a good deal, I'm just sayin', things are developing fast.)
