Microsoft Surface 4 as Laptop Replacement for Soaring Pilots?

Typical of a lot of soaring pilots, I'm swimming in devices these days (Smartphone, Tablet [Kindle], Work Laptop, Personal Laptop). I'm thinking of doing away with the Kindle and Personal Laptop and switching to a Surface 4. My requirements:

- USB Input/Output (file transfers to loggers, Flarm, Clearnav etc)
- Wifi (for those soaring devices that do/will support it and for Internet Access at contests)
- Full MS Office (so I can still see/work on documents I need for work in a pinch while I'm away)
- Supports all major soaring applications (SeeYou, Google Earth, etc.)

The Surface seems to be the answer.

Any other ideas? Note: I'm not an Apple guy, so that's out - hate being tethered to iTunes. Other tablets seem to either lack full MS Office support or are short a "regular" USB port. I hate having to carry more cables and adapters than I already do.

Note: No longer worried about communicating with old serial devices like GPSNavs; gave all those away at htis point.
