Really? They're offering me $400 for my 256gb / 2.4ghz late 2013 retina model. Pretty bog standard and 3 years old. That's enough to make me seriously consider it, since I've been eyeing the surface book for a bit. Mainly I need to figure out its Ubuntu compatibility now.
I would in a 1-to-1 deal. They are both overpriced hardware for what they bring to the table, but at least the SPro has a Wacom touchscreen which makes it a great little thing for taking notes and on-the-go whiteboarding. I would've loved one for my daily commute when I had 30-45 mins to kill on the bus. An MBP offers me nothing valuable over laptops at ~half the price.
