It's very interesting and surprising that battery life is worse than Intel. I wonder if this will get any better with driver/firmware updates?
In the mean time they've released a ton of new products and locked the 12th Gen BIOS threads on their forum (ironically, after talking about how they'll try to do a better job communicating the status of firmware updates).
I strongly suggest that if you buy one, you base your decision on the hardware and software as they are today, not on future improvements that may never come. If you're not willing to accept warts like poor battery life and nonfunctional brightness keys, you're better off getting a laptop that doesn't have those issues.
