For a couple of days I had a Surface Book 1 before returning it. The keyboard was really good but otherwise just a terrible device and experience.
replyThe touch screen was completely useless. Super laggy and sometimes the pen would still believe it was touching the screen even at like 1cm away. Windows 10 had almost no features for touch based interaction. It was just regular Windows with the same microscopic buttons for mouse.
Plus a ton of display ghosting, GPU glitches, etc.
I still have a Surface Book 1 that I occasionaly use and I never encountered any of those issues. I even used it for some sketching and there was no lag or spurious touching from the pen. In fact, sketching was why I was "drawn" to it (heheh), largely influenced by this review: https://www.penny-arcade.com/news/post/2015/11/16/surface-bo...
replyMy big problem with it is that the battery got swollen a few years ago, pushing out the bottom panel, and the device is way our of warranty to get it replaced. I'm waiting to find time to get that replaced.
