I really like the Piel Frama aluminum case. It's saved my Treo's butt more that a few times. And when I ordered spare parts direct from the Piel Frama company in Spain, they were great too. Anyway, if he stays with Treo, they're worth considering.

Here's a review (not written by me): http://mytreo.net/archives/2005/10/r...reo-cases.html

I think it looks better in-hand than in the pictures. And, on the back, there's the black screw-on attachment for the included belt clip. I just leave that attachment off and can carry it in my jeans pocket without any clip.
