I'm considering an Android phone. I've been reluctant as I like my old Nokia with the physical keys, but right now I'm lugging my big android tablet to work to listen to Pandora, which is a pain in the butt. I have an iPod touch, but Pandora isn't on it, plus it's an older one.

I'm used to writing on the big tablet, but it drives me crazy at times, even with swype - sometimes it's spot on, sometimes it's horrible. With txt you tend to abbreviate a lot as well, which won't work well with Skype. So they keyboard is the main reason I haven't gone to Android yet, that and battery life.

So here's what I'm after and what I'll use it for:
 - Android 4.0 with an upgrade path to 4.1 and beyond
 - Great battery life (2-4 days)
 - I don't need the biggest screen, I'd prefer moderate and robust, but the S3 does look quite nice
 - Probably No OEM skins (plain old Android)
 - Not sure if a physical keyboard is a good idea - it'd either make the screen smaller, or the phone fatter
 - I'll mostly use it for calls and text, with some music playing. I may play a casual game a few times a week, but not often.
 - I may use maps or check email while out and about, but not that often.
 - Shopping lists and calendaring (basic stuff)

Can anyone recommend a good device for me, or should I just stick with my Nokia and tablet, or my Nokia and a cheap iPod equilivent Android?
