Anyone have an opinion of the Blackberry Curve?

It’s almost time to get a new phone. Seems like the Blackberry Curve 8330 fits the bill, but I just want to be sure. The features I want are:

some way I can check all my email messages at once
navigation system
qwerty
alarm clock and calendar
camera
decent display of time and date
good battery life
good reception
I don’t want to pay more than $50 or so. I can get this one at Verizon for $49.99.

I’m not hard to please. Other suggestions welcome.
