It's a properly impressive piece of kit tbh, it's running all of my lab stuff now, and very well too. Makes me laugh a bit when people say the SB2 is fast - it simply isn't. If you want a laugh on one of my youtube vids you can see me do a video conversion on the Surface Book 2, and at the same time do the video conversion on my Macbook Pro in MacOS, run Windows in Parallels *AND* convert the video in Windows on the MBP.
It finished both of them way quicker than the SB2. Still, not a terrible machine in its own way, just wouldn't say it's fast!
EDITed to add, aha, not any more
Actually do use this stuff, they're not vanity toys. Honest.
