After debating about it for a while, I've decided to change to a new portable setup for my projects and work. While my Wacom Companion was a great device, it had a few downsides that made me look at the refreshed Surface line from Microsoft. I was hesitant about the upcoming Wacome Mobile Studio devices given Wacom's shakey record on quality control. After spending a couple evenings at the Microsoft store, I decided that the Surface Book refresh was a really interesting concept and decided to preorder the new Performance Base model.
TL;DR - I'll post more on this later, but in short, this is an extremely well thought out machine and is extremely fast and capable. I've been really happy with it and have found myself generally more productive than I felt I was with my Wacom Companion.
