Mine does have the "coil whine" thing, although it doesn't really bother me since I'm usually wearing headphones when I use it. But overall, the build quality is just pathetic compared to my Macbook, and this is supposed to be a competitor. The touchpad is way worse, the carbon fiber thing is cheesy, the awkwardly fat bezel at the bottom of the display is silly, the fact that you need a $100 dock to connect to external monitors is ridiculous, the webcam is weirdly placed in the bottom left of the display, there are just a bunch of strange/bad design choices.
That was all the bad things - otherwise it's better than any non-Macbook I've used. It's lightweight, small, gets the "little notebook you can take anywhere" niche fairly well. I hope they listen to feedback and iterate, but I can't say I'd eagerly recommend it.
