I would say that the Surface Book is worth the money, as well. While the bugs definitely detract from the overall experience (I would be wholeheartedly endorsing the SB to everyone who would listen if the ugliest bugs weren't present), I don't think they take away from the overall value for me. Part of the reason you pay a premium for a device like SB is the build quality and materials -- both of which on this device, are top notch.
Yes, the internal components of the SB are on-par with the competition (i5 or i7 skylake CPUs, nvidia GPU makes it more on par with a light gaming machine than a standard laptop, RAM, SSD, etc), but that's not totally where the value is, IMHO. The value is also in the construction and features, and while Surface Book has some maturing to do (yesterday's video driver update is hopefully one of many bug fixing updates to come), it's still worth every penny I paid for it. I now have the extra power needed to do faster Photoshopping, play some "real" games with decent graphics settings, and still not need 2 devices for both work & play. The SP3 I had before SB started down that path, but was sorely missing the graphics power. Surface Book answered all my needs and does so while feeling like a truly premium device. I wouldn't want to go back now...
