Having travelled across the pond to New York to see the PRS-700 (and to have a holiday). I was disappointed by the screen, compared with the 505 it is fuzzy and the side light isn't amazing. I loved the functionality of the device and the touch screen is a joy to use. Just couldn't decide wether to get a 700 or 505 so I'm left without an ereader.
Perhaps a hint for Sony, don't display the 2 devices together
