PRS 600 had glare issues. The new PRS 650 has NO glare issues. It uses Infrared beams for touchscreen and is very sensitive. It is not overpriced as it has many neat features that other devices dont. pdf reflow, pdf zooming (custom, analog, and not 150%, 200% etc., but real dial zoom), EPUB format, extendable memory, TOUCHSCREEN, good looking, library books, tough built etc. etc. I almost bought the damned device but it was not available and then I had to settle for a Kindle which sucks when it comes to PDFs. Everything else is great. And yeah agreed, it does not have Wi-fi, but it does handle pdfs better than Kindle. It can reflow pdf which the kindle cant. As can Nook too. As can any other device on the market except Kindle. So, I dont know the OP's main intention of getting a reader. If its reading science journals and tech stuff (read PDF, i.e.) then please go for Kindle DX or Sony PRs 650 or PRs 950 (when it releases). If its novels or books that are available in any other format originally, then yeah, Kindle wifi will be the GREAT device.
And, again, PRS 650 does NOT have any glare. Please check the facts again. It does not have an additional glass layer on top of the reading layer like PRS 600 had.
