Five good mapping apps for various needs

...a Microsoft Surface!

It would be cool to have that little tablet with the S&T app loaded and some clip for car dashboards.

I started with Street Atlas but quickly moved to Topo-USA for better maps and the ability to use real USGS Topos with GPS and draw property lines and drive right to them. The USB GPS unit comes free with the software. The "pro" package even comes with a national phone book with reverse look-up. I now have Delorme XMAP which allows for downloading of shapefiles for property records, flood zones, aerials, etc, etc.

I've been using Street Atlas for so many years I cannot remember not using it. It predates the advent of Streets and Trips and provides the ability to plan trips and manage travel data without Internet connectivity. It possesses extensive customized routing capabilities, the ability to annotate in multiple formats and to add routable new or private streets and roads. Like Streets and Trips, the application is available standalone or bundled with a either a USB or Bluetooth GPS receiver. There are also available enhancements options such as Phone Search.
