I am really noticing the rainbow/sparkly/grainy screen attributes as well.

I had a Zaurus 6000L with a vga CG Silicon screen, and it was absolutely gorgeous, and it included a touch screen as well. The 770 screen is OK, but if someone offered me an upgrade to the Zaurus 6000L screen for $50, I'd take it. It's absolutely stunning, seriously.

However, the Zaurus is just too damned big to carry around, and I intend my 770 to be mostly for ebooks, white on black, so I will minimize the "oily effect" or whatever you want to call it.
