Actually, let me add 2 more cents...
The screen is gorgeous. It's not super-over-saturated and the Color Profile tweaks make it easy to set up for your eyes. For OLED this surprises me how well it does in direct and bright sunlight.
The 8MP shooter takes some nice snaps.
I've been driving it daily since Cricket first put it on sale (and I do mean the very first day). Overall I prefer it to the 640 and I loved that phone.
Caveat: the battery is small. Heavy users might have an issue getting through a whole day.
