The Garmin-Asus Garminfone is the company's first offering for T-Mobile USA. With a 3.5 inch capacitive touchscreen and built-in Garmin GPS, this is more of a GPS with phone cpabilities rather than a phone with GPS capabilities.
Loaded with Android 1.6 and all the other goodies that you can expect in a mid-level smartphone, the Garminfone is a good choice for those that travel a lot or just get lost a lot. Having phone capabilities doesn't hurt either. You can pick it up with a 2 year contract from T-Mobile USA for 199.99.
