I finally gave up on trackpoint/sticks, and never did use the touchpad. I carry a small wireless mouse everywhere, it's just so much more efficient.

My Surface Pro 4 has an i7-6650U - seems to do pretty well. But MS is still sorting out video driver, power management issues, etc. I'm beta testing for my company, so I accept the issues I've had, but I haven't had issues of this magnitude with an actual in-production laptop in some time. Example - I have to disable the touchscreen to prevent Excel from crashing when I undo a filter.
