I do have scratches on my screen but it's no worse than any other resistive device that I've used. The worst ones (about 2) were suffered back in December after I first got the thing. But a screen protector is a good idea, regardless.

And I highly recommend converting this into a Wiki page and re-categorizing some of these, as (like Texrat noted) some of these are more opinion, like the 3-row keyboard and means by which you transition desktops, than actual issues like the USB port and mp3 tag issue.
