Depends. Do you still trust them with your laptop and that nothing bad will happen when you plug your data back in? Or do you just travel with your data and rely on using a machine at the other end? In that case, with USB 3 and especially Type C getting more and more traction, is it really absurd to just boot from an external disk/flash stick everywhere so you don't have to rely on the other end's OS? The major problem with that though is MS and Apple aren't especially friendly to the hardware changing underneath them. So the alternative then if you have to use them is probably having your OS in the cloud, and hope your wallet is full and your network good.
