I have the crystal protector for the screen, and this case:

The Powersupport screen attaches via static and I hardly notice any smudges, and the case is minimal. My personal reasons are two-fold:
- Protection, bascially if/when I drop the thing, it will hopefully survive with no sign of damage. The case feels very slippy in my hand (my palms are not sweaty
😛) so just a little extra re-assurance for me.
- Resell value, has had the case & screen protector on from the moment I opened it so it will resist scratches very well hopefully throughout it's lifetime. Although from my personal point of view, scratches on the back from my own usage doesn't bother me. I stare/use the screen, not the back
🙄
The screen is very very good at resisting scratches, my iPod Touch has none, but I'd rather just be cautious now and get more money when it comes time to sell and trade up. All very personal reasons, so using cases are for some and not others. Users shouldn't presume one way or another, that cases are wrong or right. I also don't give a crap how the device looks, only how it functions.
I do think also there is a very real heat problem inherent with the device itself, even if it is very small range of context. I don't like Apple passing on the blame, as they've been very good in the past admiting if something is wrong, even if very minor...
