TomTom on Treo 700wx

I am running TomTom Navigator 6 on a Treo 700wx and compared it to a TomTom ONE XL. Although the ONE XL is a dedicated unit, it seems to be a bit underpowered. The software performs better on the Treo. I noticed this in 2 areas.

1) Navigation animation - The position is updated much more frequently on the 700wx. This makes it look a bit like a video since the position is more smoothly updating.

2) Route calculation - There's not a huge difference here, but the 700wx did calculate a route of moderate length(Maryland to North Carolina) 1-2 seconds faster.

Despite losing the nice large screen of the ONE XL, I prefer to use TomTom on my Treo. It runs better, and it's just more convenient. I can just leave my bluetooth GPS receiver in the car, and the Treo is always ready to go. No need to worry about bringing along another device.
