I'll take more pixels over more inches every time. More pixels mean documents are that much sharper and easier to read. Are books hard to read even though the text is small? No, of course not, and that's because the text is sharp. If you want the sharpest text at any size, you need to go for the greatest number of pixels. Now if there were a nice lightweight SXGA+ 14" tablet, I might consider it, but since it's already available in a smaller package that's easier to carry around and easily manipulate one-handed to show things to my peers, it looks like I'll be sticking with 12" screens unless someone pulls off a 14" tablet that can't be matched by a 12".
