Without competition. It is certainly powerful and does not make any compromises in terms of performance, and now even with a surprisingly good runtime of 10 hours. The Book easily beats the competition. But: Surface Pro 4 Core i7 and the i5 sibling are in the same ballpark – except for the runtime, which is a surprise.

Thanks for this useful review but after read it I think you should consider another review of the i5 version with the correct updates of bios and drivers...is hard to believe that an i7 has a better runtime than the i5 with the same specs and battery capacity.
From review I can't ubderstand for shure what does it mean:
The brightness fluctuates on mains.
You found those fluctuations with power adapter attached?? At all brightness?? Or what?? Please, specify that problem more detailed!
I love this product. But the screen is uncomfortably hot against your hand when you naturally rest your hand on the screen while you use the pen. Until Microsoft resolve such a fundamental usability problem, I can't see why anyone would spend the money on this product.
As soon as they do however, I'm first in the queue! I consider this to be the biggest challenge Microsoft face with this product. It will be the hardest to solve...
