Just as a quick note, the original Droid/Milestone is metal, with a gorilla glass screen. I don't even use a case on mine. It has an awesome keyboard as well. It has this wonderfully comfortable sense of "heft" to it...heavy enough to feel solid, light enough to hold it to one ear for long calls.

Sadly, I bought the Milestone, so I was snookered by Motorola's secret locked down firmware. Droid users were pretty happy with theirs, their firmware was open and they can still update it as new ROMs come out.

The Milestone's version of Android tends to be buggy and Motorola is competing with Nokia as far as who can put out the slowest updates.

Still, metal Android phones do exist, you just have to watch for them.
