If it was me I'd go with a Surface Book with Solid State Drive (SSD).
You can use it as a laptop and as a tablet and you can easily use the tablet as your GPS! Bonus!
I'm not sure about that... I don't believe the Surfacii come with GPS, at least not up until the Surface 4 last I looked. Please correct me if I'm wrong and direct me to where I might purchase one with GPS... Much want.
