I've got both (older models) and if I had to choose one I'd stick with MBP. You can run MacOS or Windows on it (I'm primarily a Windows user). 15" hi-res screen is more useful for dev work than 13" super-res screen. Touchscreen of SB is more useful than I'd have thought but far from necessary. The detachment mechanism of SB is a bit too slow and clunky to be useful, and you're still stuck carrying a keyboard around (plus Windows doesn't have much going for it in tablet mode). I'd like to see them go toward more of a Lenovo Yoga route with the next release. That said, I probably use the SB more than the MBP these days, because I mainly use a desktop for dev work, and the SB is smaller and more convenient for non-work tasks around the house. But if I'm working remotely for a long time then the MBP is absolutely the device I'd take with me.
