OP, good luck on your new phone!
I think many of us are going through our iPhone withdrawals right now. That's how fickle phone collectors are. We want something new again.
Had my iPhone for 14 months now. Jailbroken and all. Getting bored of it. I actually don't use it as a phone anymore, just an iPod touch to surf the web and take notes. My Nokia has superior call quality. No echoes. I'll probably still keep my old one since Apple knows how to ball-n-chain you with their apps, OS, high storage capacity, and iTunes.
I will still get another iPhone in the future. Maybe the 128GB iPhone if they ever released it next year. 128GB would be more than enough for me for at least a few years without needing HD videos.
But the technical hardware has been clearly surpassed by these Androids. I want either the Nexus One or the Xperia X10. Only knock is the storage space and the less polished OS. The Android Market will evenutally grow though. The hardware is there, just not the apps and slick OS yet.
I personally think the Palm WebOS is still slicker than Android. But Pre's processing speed is already outdated, and the app store and build quality leaves alot to be desired.
Nexus One vs Xperia X10, still undecided. That UI for the contacts looks slow on X10, but the camera might be better (has shutter button), as well as the multimedia apps. Love both their names though. Nexus One or X10 for the year of 2010: 1st year of a new decade...
