I've been playing with the Colorsoft and agree with most of your comments. I don't see the "screen door" effect and there is slight yellowing at the bottom of the screen. I've been able to twiddle with the lighting and find the screen really nice - comparable to the Oasis, better than the PW 11 in terms of contrast.
The book covers are a novelty that I really like, using the "vivid" setting makes a difference. I sure wish it had buttons.
