As promised, T-Mobile has brought the Garminfone to retail today for $199 after $50 rebate on a new two-year contract, calling into question the viability of selling a nav-centric Android device with an HVGA display, 3 megapixel camera, and no 3.5mm headphone jack for $250 out of pocket in the store. We suppose the awesome car dock will attract some, but the myTouch 3G Slide certainly seems like the better option for less money -- maybe this would work at $99 or $149, we suppose. Not that we're impatient or any
