jimphall, welcome to Laptop GPS World. That's a nice machine! How much extra is the the version with the daylight viewable screen?
Just like Terry said, I think any
GPS software for laptop will do just fine.
This seems to be the first laptop to support multitouch, so lets hope more screens will soon support it, and PC GPS software developers will add some support for it in their existing products. I think it would be neat to be able to change zoom level with two fingers.
