I have the enV2.
Things I hate:
Restarts when you take a picture and immediately try to send it, but only if you have a card in.
Pocket dial all the fucking time.
Things I like:
QWERTY keyboard
microSD slot

So the things I like are the same as the voyager, and the things I hate are fixed in the voyager.
The enV2 is a lot thinner and shorter than the voyager.
