The "heavy-industry" tone of the design just really appeals to me, and the Verizon commercials were cool (especially the stealth fighter one).

I really like Motorola designs, but the locked bootloader means a no-go for me right now. As awesome as HTC hardware specs are, the designs just don't appeal to me as much as the Droids.
There is a little bit of hope though.
Speaking of Motorla, here's a Wired article which I found a good read:

Despite marketing the droid as hacker-friendly and open, the locked bootloader is a real kick to the nuts. As everyone tried to distinguish their Android device by adding in more and more software/UI enhancements, Motorola should really knock out a feature-packed vanilla Android handset that will receive future upgrades; A sort of Motorola Nexus. That alone would distinguish them from everyone else.
