Re: Doubt it
A lot of people who use Linux wouldn't buy it just because it was made by Microsoft, irrespective of how well it runs Linux.
Which is a rational thing.
No other manufacturer has an inherent interest in making sure "alternative" OSes don't run properly. The rest of them just want to sell hardware. Microsoft wants it to be a showcase for the latest Windows 10, and that means that even if it runs Linux well now, there's no guarantee that the next firmware update will not do something to sabotage that. MS has already shown they're not above such practices. Given how troublesome these things are, you'd possibly be in a situation where you had to choose between having a firmware bug fixed or being able to use the OS of your choice.
Then there's the price of the MS devices, and their poor repairability...
It would be fun to run Linux on one just to flip the bird to Microsoft, but it's only a little bird... perhaps a hummingbird. After all, they still got your money for the Surface AND for the Windows that came preinstalled, even if you don't use it.
