I am not really concerned with the TP2's GPS lag when driving, its when walking it drives me nuts! I really like Geocaching, and I use a few apps to help with paperless caching. One in particular is GCz (Version 2) and google maps. I dont really notice the lag when I am driving to a cache, but once I get on foot, you have to walk 20-50 feet before the gps updates your position, which can make caching "challenging"
What exactly does GPSgate do?
