The 6800 does not have too many advantages over the 6700 as far as features go. It does have WM5 AKU 3.5 and a 256MB flash storage instead of the paltry 128MB that the 6700 does. The really money is in the processor. The 6800 has the Qualcomm convergence series MM7500 model processor which is essentially an ARM11 CPU for the PDA functions of the phone and an ARM9 CPU for the EV-DO functions. Since data transfer is offloaded to a different CPU, it should show some promising speed with network applications, specifically TV and video casts.
