My relative has an Asus T200TA. As of Linux 4.4, the system runs like crap. Freezes, wireless overheats, some detectors cease to work after suspend.
And even if they (or the community) make Linux 'work' it doesn't mean Linux software is optimized for the hardware / small screen.
The price won't be optimised either. $300, how much of that is a Windows license? I doubt the Microsoft tax would be negative like on big desktops/laptops.
