So could I just ask what difference have you seen on the battery performance issue? Getting anywhere near the quoted 9 hours on this new machine?
My Surface is usually plugged in so I don't have much battery life data. The best example of the severity of the problem for me was that I charged it overnight, put it to sleep, unplugged it and drove 20 minutes to an appointment. When I got there, it
wouldn't wake up, it was so dead it wouldn't even tell me the batter was low.
Since replacing the machine, I've taken it to several similar meetings with no battery problem. (I did once have a pen problem, thinking it needed to be charged, and I didn't use the machine. When I got back into the office I researched how to charge the
pen -- it is passive and doesn't need to be charged -- and realized I should have just tried some basic things -- lock/unlock the screen, put it to sleep, etc. -- as the pen worked fine when I got back to the office.)
I hope some day soon to be able to rely more on the machine. It is pretty amazing but the experience definitely has me not feeling like I can rely on it yet.
