I've heard about (don't have an Android phone yet, but will be getting one soon's I get my tax refund) using Google maps and the Optimus M has the Metro Navigator and such. The phone has gps capabilities and so on. My question is whether this is a suitable substitute for a stand alone gps? We are planning on buying new phones and going with MetroPCS and getting a GPS with our tax refund this year. Any thoughts and ideas are greatly appreciated. Al F.
