I have the 6800 and I am going to be switching to a Vogue. While WiFi isn't must for me I am probably gonna buy a MicroSD WiFi card if they ever come out.
I like the Vogue because of it's size, TWICE as much RAM, Flush Screen, not too many overheating issues like I have with my Titan.
I would ditch the Black Berry completly... there is no software for any other OS like there is for WM.
So...when it comes down to it, get what is best for YOU
