I wasn't really surprised by this, I've got a Surface Book (ordered after the announcement) and so far have been very pleased with the hardware, and hoping the software can catch up. For me, to replace a paper book and paper notebook you have to have a great reading experience and a great drawing experience. For me, the Surface Pro 4 has both of those.<p>That said, I'll probably end up getting the tablet version to augment the Surface Book unless they can fix detach. Way too often I try to detach and it won't because something is unable to release, and when I'm in "clipboard" mode there are <i>no</i> ports on the clipboard. I can get around that partially by using the dock which has ports but I'd really like a USB-C port and a micro-SD card slot on the display half.
