Some k to komugi for finding the 300/600 J&R preorder page and igorsk for reporting the manuals.

Hope they get some pictures soon. The 600 specs look good. I purchased (and still love) the 505 over the 700. If I jump to a 600, freehand notes/annotations, dictionary support and additional memory would be the primary motivations.
I'm not craving touch screen per se other than for the virtual keyboard and freehand notes, but touch screen navigation seems like something that might grow on me after while. BTW, I'm also in the don't-really-need-wireless camp. But I can understand some being attracted to Kindle Whispernet if they need quick/anywhere access to periodicals, book club recommendations or bestsellers--which I don't.
Of the course the 600 display has to be at least as clear and sharp as the 505 or Sony has wasted a lot of time and money.
Most of all, on behalf of blue PRS 505 owners, I must say it's a tremendous mistake if Sony discontinues blue! Maybe go with a true navy, or grayish blue instead of the purplish blue, but don't eliminate the bestest, smartest, most evolvdest color in the world! And don't try to tell me it wasn't selling as well as red.
