the Vu and dare are practically the same thing, the Dare is a bit newer, better GUI, better camera.
It's basically the poor man's iphone. Music is ok, need an adapter use headphones. Doesn't play videos very well (like movies or tv shows). Camera is pretty good.
Texting is sub-standard, if your used to a good keyboard you will need to slow down...doesn't pick up correctly most of the time. No touchscreen keyboard is as good as a real one.
It's ok. I'd go for one with a real keyboard though...maybe wait awhile, the HTC Diamond Pro looks good, as does the new LG Prada (Vu in Europe) 2.
oh and btw, the Vu scratches very easily. Not the screen, but the back looks like shit after a few weeks. Just having it in your pocket scratches the shit out of it, so i'd assume even a case would put micro-scratches in it too.
The TV is eh. Channels blow. Don't show syndicated shows either. Commercials are lame as hell.
Does look sweet though. Stylish phone.
