What it comes down to, Euroboy, is . . . to touchscreen or not to touchscreen. That is the question. Both are fine devices, but it all depends if you are one of the few people who can't stand the slight glare on the 600. I personally don't mind it. The 600 has much better features, faster speed, dictionary, note-taking, etc. And the 600 is better for PDFs because you can zoom in and there are more text sizes.
