When Google does put it out, I dont think it will really bother them. Googles GPS is OK, but Tom Tom, Garmin & AT&T Nav (Telenav) are rated way above Googles GPS. Also Google uses Cell Site tracking & not the GPS satelites Tom Tom, Garmin & Telenav uses. I will say I do like the street view feature that Google offers on the Droid, AT&T Nav (Telenav) also has that on the I-phone also. I will say that Googles GPS system is getting better, but has more room for improvement.(As do all GPS systems)

Your somewhat correct with how AGSP works on AT&T. The GPS data for AT&T (Telenav) data is from the satellites, & the mapping data is being sent via the data network from the carriers. I was able to meet with Dr Bob Rennard, one of Telenav’s founders, & he explained to our group on how this works.
Also, The Verizon Blackberrys (On the Market Now) have GPS chips. Yet VZ Nav is all from Cell site GPS. So software is a big factor for the type of GPS services available.
Please note.t...
