Just came from an hour drive and tested how the gps works compared to the tp1 and so far I would say its a little better than the tp1 as far as lag. I used sprintnavi, googlemaps and msn live search. For the most part my position didn't lag behind too much at all and more importantly after about 30 to 45 minutes using gps while it was charging there wasn't any noticeable heat(slightly warm) coming from the phone.

Also if you have a mogul leather case laying around that works perfectly, atleast it did for me.
