I have an Android, a Samsung Epic, Sprint calling plan (unlimited everything). I hate it, am hopelessly unable to use it. I'm not saying it's a bad phone - I don't even know enough to judge that! I can just about manage to make calls and answer them. Oh, I can get on the web, in a limited way.
I can't figure out how to put someone on hold and answer when another call comes. I can't figure out how to drop the voicemail I'm listening to, to get to an incoming call. It makes me literally cry! I can't get it to do anything I want it to (keep the screen on so I can see when the bars are going; make the sound of the caller's voice louder, not the ringtone; let me check my email without checking it for me...)
The Epic's battery needs constant recharging. I replaced a Wal-mart phone because I never got many bars when everyone else was talking away. Best phone, decent plan, still same problem.
So I can't give you much good input, except about the battery.
