I own both and have spent a lot of time with both PPC's here is my evaluation. The 700wx hasn't really left my side since I got it. I thought it was just because it was new, but its not. I tried curring the 6700 the other day because I had made some changes that I wanted to test. Large screen, nice key board I was falling in live all over again. Than I started surfing the net, slow downs and it froze on me. I haven't froze the 700wx in a long time. Really the 700wx never freezes the only time that it has is if I am ruining some software that is a beta or not made for the Treo. I miss some things about the 6700 but there is on way I can go back and be satisfied. The only way that I can explain it is that the 700wx just works better. If you have time and want a fun PPC to play with and experiment with that has all the power you need go 6700. If you need a PPC that works smooth and gets the job done flawlessly go 700wx.
