Re: How much?
Anyway: I would wait until someone reports that Linux Mint runs on it.
I did this a couple of years ago with an Acer Aspire One cloudbook; they shipped with Windows 10 which it was far too low specced to run properly on at all, and so retailers were awash with returns which had basically been booted up and then sent straight back. I picked one up for less than half price, put Mint on it and it ran perfectly.
