There's no one-size-fits-all solution. Since both Android and iOS have parity for basic functionality either would be a good choice. For third party apps most of the interesting stuff is still happening on the iPhone. There may be equivalent Android apps (ports or clones) but in my opinion it's still a second class platform. Especially when you get into multimedia apps, creative apps, games, etc. On the hardware side the iPhone has probably the best display out there and one of the best cameras. Availability of regular software updates are worth considering too. If you want the wild-west experience there's a pretty healthy selection via JailBreak. If you can wait a few months it may be worth seeing which phones are going to get Android 3.0. The N1 probably will but all bets are off with HTC and Samsung. I'd say most of their phones sold today will get it eventually but who knows when. Both HTC and Samsung totally dropped the ball on the 1.x->2.x transition. Motorola hasn't experienced a major OS update yet so it's not clear if they will be better prepared. The gimping of 2.2 features for the original Droid is not an encouraging sign. I would suggest a Super AMOLED screen if you want to use your phone outdoors. Maybe wait for the next device Google adopts as a developer reference platform?
