Ok, how do I begin... I have had the $2699 Surface Book since Day 1. Since then, I have gone back to the MS Store for exchanges due to sleep/short battery life issues (6 hrs -> half of the 12 hrs promised). I am now on my 4th unit; and still, after all the updates thus far, nothing power-related has changed. Yet, the guys at the store keep saying that I shouldn't have these problems, as if they weren't normal. Now, I stopped believing that I was just unlucky in receiving bad units, and convinced that the product is inherently flawed. It saddens to say it. I'm well past my time frame for a refund, but a quick Google search tells me that California's Lemon Law extends beyond autos to virtually every product. Should I go back and ask for a refund?
