Yea, I see how 10" would be great for reading more books with graphics, however 7" i think is a perfect size for a tablet, especially to hold with one hand.
I am also hearing a lot of great things about Acer, and am considering switching over. But I definitely will never buy another Lenovo product again. I saw this article and was not surprised in the least:
Lenovo Sucks.
Battery life I have come to realize just sucks on most of these devices and either way I am most likely going to charge it everyday.
I just hate that more and more of these tablets keep getting replaced and still don't know which to move over to. I have been reading a ton of articles on which to buy and the benefits of each.
