My First Day with Microsoft's Surface Book

Last month, Microsoft wowed many of us with their unexpected Surface Book announcement. I certainly sat ooh-ing and aah-ing at my desk, sending instant messages and tweets to everyone I thought might care. What those messages said: “Microsoft just made the laptop I crave!”
Over the past year, I’ve been using a Surface Pro 3, a Macbook Pro, and a Samsung ATIV Book 9 Plus (what a name!). In the interests of full disclosure, I’ve always preferred Windows to OSX. I use the MBP for Xcode and Ruby development, because it’s required by universal laws and such.
