The Surface Book 3 may give the XPS 7390 a run for the money for the high end enterprise users. My initial concerns will be heat, weight and build quality. XPS metal body feels great and is durable. I wonder how this will compare.
The hinge is the biggest thing. Because it connects over PCIe to the base, the Book is very sensitive after a decent amount of time. If I adjust the screen, the hinge disconnects and reconnects.
Also, if I unplug my headphones while it's sleeping in laptop mode (which I use 99% of the time), the audio cuts out and I have to restart the machine.
That's why I'm typing this on a Dell Latitude with the same 6300u that's inside the book and with a worse screen -- at least it generally works even if I had to re-uninstall Candy Crush...
Cute concept, garbage execution.
I hope they get it right this time.
