Don't know what the Samsung is like. It gets excellent reviews. I did read that ATT blocks you from installing 3rd party apps which I would have to check - seems nutty, why would anyone buy an Android Phone if they were limited to ATT's own apps?

Blackberry doesn't have a lot of interesting apps, as far as I know. I think the hardware is good though my last BB experience was a while ago.

I like the Palm Pre. It is the most phone-like of these, and the OS is good, has a physical keyboard too. I don't know if app availability has developed since Palm has not been able to get much market share.

The iPhone will do everything you describe.

However, what is "moderate use"? The battery on these phones will not last all day if you are browsing the web much of the time. Example: my iPhone is fully charged, I leave the office at 3pm and get on the light rail to the airport, 30 min ride and I'm browsing web the whole time. Check in, wait 1.5 hour for (delayed) flight, and browsing the whole time. Get on flight, listen to music for 1 hr. Take BART to hotel, 40 min ride, browsing. The phone has 48% charge by the time I get to the room. That's a bit less than 3 hours web surfing via 3G, 1 hour music, 1 ten-min call, and almost everything switched on (3G, wifi, gps, not Bluetooth) except for the flight. That's a typical real world battery experience for me.
