Nothing particularly new, but I am comfortably in the boat of people that don't feel that laptops need to be reinvented in any major way. 95% of what I do is in the command line, the browser, or an IDE. I've consistently gone back to my MBP to do all of those things after having tried many other form factors.<p>That being said, I have to admit that I am at least intrigued by the Surface Book. I recently tried the Linux subsystem on Windows and was pretty impressed, it's literally just Ubuntu running with file access. The fact that I CAN pop off the tablet portion, and if I'm so inclined for art, have Photoshop, Illustrator, ZBrush actually available to me is pretty tempting. The OS differences between OSX and Windows for me have always existed only in the command line, so as long as Windows gives me bash and Linux, that pretty much disappears.<p>Conclusion is, I don't think Apple is suffering from a lack of innovation in the laptop department. I don't understand why people assume that we haven't yet converged on the optimal form factor. Why I chose an MBP for my current laptop wasn't because it offered anything totally innovative. It was already derivative of 30 years of laptops with the same form factor. I chose it because of the Unix development environment and the great build quality. I've never used a Surface Book, but it seems like Microsoft has stepped up their game in the build quality department. If their trackpad is as good as Apple's (I have yet to use a Windows laptop where this is the case), then I'd start to consider it a serious competitor. If the two have comparable build quality and Unix, then their form factor innovation is going to be the only thing left distinguishing them (for which Microsoft is obviously currently ahead).
