Pros: Reasonable price, fast EVDO access, good sound quality, Easy to use menu.
Cons: GPS freezes frequently, you can miss an exit. Not multitouch screen, lacks the finesse of the iPhone screen. I had trouble w/activation - took 3 days to get the data working!
Summary: I wanted an iPhone but all my family uses Sprint, I need to stick to Sprint. So I waited. No the Instinct is not an iPhone, but it provides all the iPhone features (albeit w/o the elegance of the iPhone multitouch screen - touch and graphics) and then some more! Plus you get voice commands, user replaceable battery (2 provided), an external battery charger, micro SD card - up to 8 mg support, Video camera, & live Sprint TV. Overall I am pleased and happy with my new phone!
I did experience problems w/activation. Not sure what happened, but it took Sprint support 3 days to get the data portion of the phone working!
Now I love it! Love having my email instantly!
Wish list: IM support, an icon for YouTube, and would like to be able to have more control of the menu, like moving icons around, and to be able to add anything to the favorites screen.
