I have a Surface 3 (not Pro) that I absolutely love. It’s fantastic for life on the road, as I have full access to all my Office apps, amazing battery life and light weight. It’s a little (a lot?) underpowered for gaming, but I can still run a few older games on it just fine for the times when there’s nothing appealing on Netflix.
And I still use my Day 1 Surface RT as a Netflix/Plex terminal on the treadmill!
I would love a Surface Book, but they’re a little (a lot?) too rich for my blood. My wife would have my nuts if I came home with one of those. Huge fan of the hardware.
