I don't think 540g (902) is unbearably heavy but one has take into consideration the size and shape of 9"7 readers. Unlike books, a big E-reader is one big flat solid piece that can't be held in one hand. An opened book, even a hard-cover, is often easier to hold at the spine. So weight plus size and shape decide 902 won't be comfortable for reading in bed at least. If I have to read in front of a desk, the only advantage of an ebook reader over a computer is the e-ink. But computers are much easier to operate.

Just my 2 cents. I don't have 902 or any other e-reader of that size. Even my 602 hasn't arrived yet. I tried to convert my pdf academic e-books. The results are very good except that the italic won't show. I cut a piece of 12*9cm paper to try on files shown on the computer screen. Most scanned pages also show very well in the landscape mode. The words are at least as big as those in printed books. But my books have little to none graphics.
