I didn't even know the surface book was ever supposed to be a detachable.
I would just see them in stores and be confused why Microsoft put the surface branding on a crazy-overpriced laptop that has no touchscreen
What's worse is that the pointless overpriced laptop exists too, but they call it a surface laptop.
I don't know. I bought a first-gen surface pro back when I was trying to find any use case where Windows 8 was actually usable.
The ux/ui was still terrible, too bulky to be a tablet, and the "wacom" stylus was too laggy and imprecise to use the tablet for drawing. Microsoft advertised a Leatherman, I expected a Swiss Army Knife, but I received a Peltzer Bathroom Buddy.
So I don't really have any intention on ever trying another Surface product.
I'm not even really sure why Microsoft bothers with minor revisions in this product line. They aren't price competative with non-apple products, they aren't popular, and they are no longer pushing design boundaries. At least Zune actually had some things that it did better than ipod.
