Smartphone GPS

[jrnsuz]

I have recently read several articles regarding GPS apps for smartphones. Claims have been made that the most recent apps work the same as a dedicated GPS device, although I'm sure with more limited functions.

 Since I'm finally considering a cell phone upgrade, is it worth going to a higher end phone that can handle these new apps and have expandable memory, or are these apps just another money-maker for somebody?

I am not much help but you might want to see what the gps manufactures are offering to support Smartphones.  Here is a link to Garmin’s plug and play Bluetooth application for Smartphones.

The gps units are pretty cheap at pawn shops. $35-50 vs. $200 or more for a smart phone. As for apps I have never used one, but google maps website on my iPhone is exactly like my Tom Tom. Shows a little dot running down the road real time. It also has satelite, map or hybrid views. Personally I would just buy a gps because it is cheaper, but the google maps I use is just as good for driving directions.
