Size, Memory, Speed.
There you have it! Windows Mobile 6.0 is already being released in europe. (see)
http://www.europe.htc.com/ so its only a matter of time before we have it on the 6700/6800. someone will get it hacked sooner or later. sprint is in negations with HTC and Microsoft now to provide WM 6.0 to there customers. so it looks like that wont be an issue if were patient. so at this point its a matter of a little less size, a little more memory and a little more speed. plus the bragging rights that you have the best Sprint has to offer! and what the heck it just looks better
so like it has been said before I'll be there on release day wallet in one hand wiping the slobber off my chin with the other
