Android is the OS not a phone.

I'm not sure what some good productivity apps are off hand but I know they exist.

Idk what data pack you're referring to.

There are plenty of custom roms for the hero (and I'm sure there are for the Moment but I'm not as familiar with that)

There are many different programs for tethering in all the different ways (wired, BT, or wifi)

Again, differing on each phone they all might multitask better or worse in comparison. My Hero seems to multitask quite well, I've had 4 up on it pretty easily.
