I pretty much only ever use my Surface (which is quite old now) for RDP'ing into my office desktop machines to give demos - usually via a 4G connection as a lot of places I visit don't have a public wifi network.

Only problem I've ever had was when I accidentally pulled the ethernet cable out of one of my PCs as I was leaving to give the demo....

Edit: Only other problem I had was constantly losing the Surface video adapters - solved by attaching the adapter to my Surface power supply cable with a cable tie.
