That's why I wold really love to see them come out with actual GPS hardware as well as a downloadable map solution. I have no doubt they would kick Garmin's butt.
Unfortunately, I don't know if the market is big enough for Google to step into hardware. If the Google Map app starts to use the GPS circuitry as well as cell-tower-based in the new cell phones (like Scribe suggests), then I see the consumer car GPS market drying up. That could really hurt Garmin, and really only leave them with the "outdoor" GPS market. Is that a big enough? I don't know.
I think building a more water proof and shock resistant phones (or isolation carriers) is more likely than Google actually producing hardware. Unfortunately. But I support the dream of a Google GPS Unit with Downloadable maps.
