The iPhone wasn't worth of interest for me: way too restrictive. I'm not as idealistic about Open Source Software as when I was a college student, but the iPhone is so restricted it's not even about ideology, it's about real restriction that get in your way daily. Unless you're willing to jailbreak it, and forget your warrantee, and have to be careful when you update...
Android on the other hand is interesting because it's open like a computer. Not because it's Open Source, but because you're free to install any app, and anyone is free to develop any app. Tell that to a guy from the 90's and he'll tell you "well, of course you can install whatever you want on your device??" but on mobile phones, that's not obvious...
I read people wondering how the "Android Market" will work. Full of crap? As restrictive as the iPhone catalog? Well, that's easy: they can make it as restrictive as Apple if they want, because people will still be able to install app that are not on the "Android Market". Heck, one can even launch its own "App Catalog" with a different policy. And I'm sure that's what's going to happen if the Android Market is too restrictive. It's funny how people are afraid of freedom, but they were free to install what the heck they wanted on their DOS/Windows/MacOS computer for decades.
I don't hear it being available on retail without a plan, and that sucks. How can they talk about freedom if you can't even choose your phone operator... And have to sign up for a 2 years plan?
The keyboard looks really cool, and on the top of that doesn't seem to make the phone itself that big (like a Sidekick)
No VOIP out of the box, and that's kind of a deal breaker for me. My next phone will have WiFi, and it will have VOIP so I can do free calls when I'm in the range of a WiFi spot. And I want it to be well integrated to the system, so I can browse my address book, select a contact and choose "VOIP call" instead of just "call" if I want to. Currently, it seems like only some Nokia devices have this functionality. I feel like Symbian is in its end of life but if it's the only system that does what I want, well I'll have to go for that.
So, in conclusion? Android looks really cool, the G1 looks really cool. I think I will buy an Android phone in the future, one or two years from now (unless the whole Android stuff fails miserably). I'm waiting for:
