I got a sweet deal on a spanking brand new 8520 yesterday. I have a T mobile flex plan so I can't get upgrade deals. This device cost me 200 dollars. So far I noticed that the speed is way faster than my 8320 and the touch pad is SWEET!! Ive read some negative comments about this device, and maybe Im too ignorant to know better, but I really like it and to me it feels like an upgrade from the 8320.
