Long time BB user here.
Wanted an Android and went with the EVO. Screen didn't wow me, camera was really less wonderful than expected and video playback disappointed.
Speed of the phone was wonderful, browsing while on the road for work was so fast and easy to read that it often prevented my laptop from coming out of the bag. E-mail was a bit slower than the BB but it was fine. Overall build quality of the phone was great although it was kinda non stimulating.
Sound quality was so so.
Returned it for a BB 9650 for one reason only.....after 2.2, every time I answered a call or clicked "enter" to get onto the web the darn this shut down completely. Corporate store reloaded it twice, we still had the issue and they had no more EVO's.
EPIC draws me for the screen, video playback for stuff I might shoot for work, camera images appear to be better, (an 8MP camera in EVO vs 5 in EPIC absolutely does not make it a better camera on a chip this size).
The form of the phone for whatever reason appears more interesting.
More than anything and especially given that I wear hearing aids...I want to see how it functions as a PHONE (originally intended communication purpose!)
Time will tell if it's really a solid device. If they made it as great as my Samsung LCD TV's I'll be a happy camper
