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...

My 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.
