For me it's still software, the hardware is definitely solid. My experience is from when Windows 10 first came out so maybe it's all fixed now. The process to upgrade involved waiting for the bubble to pop-up in the bottom right. It didn't after a week so I had to search out the command line incantation to make it show up. Once I got it to show up, it did nothing until the 5th or 6th restart. Once it started to install it took 3 days, running constantly, on a brand new Surface Book. After that I remained unsold on Windows yet again.
