Let's hope they learned their lesson with the easily cracked/broken screens people had experienced. I don't know this from first-hand knowledge, but I remember when I first joined this forum that there were quite a few people upset about how fragile the screens were (though from what I gathered, I think the real issue was the size of the screen and the fact that it could flex too easily). A 10" screen would be phenomenal, but while $650 is a bargain compared to their original, it's out of my budget.
I, too, think they're getting this thing out ASAP to try and trump $ony's release and I don't doubt Plastic Logic has them more than a little nervous, especially if they can supply a system larger & cheaper than theirs (let's hope it's a lot cheaper!).
