AMD laptops with Vega are becoming more available [0]. I'd guess, with all the positive media push around AMD, we're going to see a lot of new AMD laptops hit the market later this year into early next. I mean Intel's latest NUC even has AMD Vega in it. NVidia shot themselves in the foot with regard to a horrid Linux driver experience. In general it's fine for desktop systems but when you're forced to log out of a session to do a driver context switch on a laptop it gets old fast.
