That's interesting to hear, because I've been using a Surface Pro for the last year and never had a similar issue. OneNote (when I use it) has generally been pretty solid sans some weird account issues that didn't take long to solve. I'd never give up my full computer for a tablet to do actual work. It has the flexibility that I can use all the normal dev tools, and then switch over to Gamemaker, etc. I honestly think using an iPad for real development is basically limited to web stuff, because you can't access Xcode to make an iOS app, or Qt for a desktop application, or even Gamemaker/unity for games. It's a "limited" tool. Don't let that single crash taint the surface line of products, because they are solid. A friend even decided to get one over Black Friday and is loving being able to write code again, as his desktop is hooked into a tv for games/entertainment.
