total noob here needs some basic explanations

FWIW, I've read a ton of people who've flashed WM6 to the 6700 and they nearly universally say it's too slow to perform well... WM6.5 is another step beyond that, and might be SERIOUSLY frustrating to use on a 6700...

If I were you, I'd look at getting a 6800 at least, and really, probably a touch pro, if you want to use 6.5
