Hello,

Here is just a thought. I am not a PC pro, but here are my observations as well as posts from here and XDA site.

TP uses the same chip set as the older models, such as mogul, tilt ....
There was no lag using previous devices.
The TP GPS position is accurate when stationery or moving slowly.
Lag increases with increasing speed with most apps, including live search, google maps, Sprint TeleNav.
Voice commands are usually very accurate and on time.

The big difference between TP and older devices is the screen. Resolution is much higher, and so it has to process many more pixels.

Could the lag be due to the display delay, not the GPS module.
Can that be solved with better drivers or ported drivers from other devices?

Any thoughts?
