Even the Droid? The Droid has better hardware in it than the Moment and a bigger install base, of course it is going to keep getting upgrades.
Clock for clock from Cortex to Arm11 yes. But the Moment is about as fast as the Droid, just with a locked visual processor. The Moment has decently sized rom space. The My Touch is also getting the 2.2 update even though it's still on Arm6. The Hero runs the same. Eris isn't going to be supported by Verizon much longer(No surprise, Verizon is known to kill support for phones fast) but the Droid is still going to be supported. I'll give Verizon this, they're keeping the Droid up and running. Sprint is basically throwing the Moment and the Hero away, which is everyone who bought one. It wouldn't be that big of a deal for me if it weren't for some reasons...
1. 2.2 adds flash, and also JIT native.
2. I bought the about 4 months ago for $60. Thankfully I had insurance on it so when it was stolen from work I got a replacement
refurb model for $100. So I basically paid $160 for a phone that is going to lose it's support soon. The Moment also retails about $500 new, $200-$300 used. That's a lot to replace it if I didn't have insurance. I bought a Palm Pre before I had the Moment for $130 used. The Palm Pre is still getting updates and isn't set to be EOL soon.
3. The Droid was released about a month earlier than the Moment, still supported.
For me, it just seems like that the Moment and the Hero were the stepping stones for Android from Sprint, to gear them up to other devices. Which isn't bad, but when you kill support for the phone as fast as they are planning to, that's when it's bad.
