Does it overheat? Does it have a fan? Overheating and fan noise are a couple of the biggest complaints I heard about the Surface Pro 3.
Seems like it doesn't have a fan, but until someone actually tests the device there is no real way to know if it will overheat or not.
Other question would be whether processor is powerful enough to handle Windows 10 desktop applications (I am not talking about games, but even Skype is CPU hungry nowadays)
