I've recently got a PRS-600 as my first e-reader. The glare issue doesn't really bother me. As others have pointed out you just tilt it a bit to get rid of it.
I think it's a minor inconvenience that for me is easily offset by its touch screen functionality.
An area that could deal with improvement though is the screen contrast. At night in low light locations the background is a bit dark. Not terribly so, but enough that I will probably get the Sony cover with a built-in light.
Overall I'm quite pleased with it. I used to print out stuff off the web a lot to read on my commutes, ... now those days are gone!
Actually, I'm realizing a kind of downside to e-readers. They just turbo charge your reading addiction!
