We're talking about Linux. If you want Linux on an ARM tablet, buy an Android tablet and jailbreak it. You don't have to buy a Windows tablet (unlike, say, PCs in the 90s).
And there lies one mistake MSFT is making. I definitely wouldn't pay good money for one of these if it can't run anything besides Win8. Perhaps only if it has a well supported jailbreak.
People who immediately remove your software (and sometimes ask for a refund) aren't a good target market. Seriously, why do you want to buy a Windows tablet and remove Windows? Why not buy what you actually want?
Because with Apple and MSFT requiring UEFI locked ARM devices, how much choice do you think will be available for people looking to buy ARM tablets they can run any OS on?
Sorry, I thought this was a post discussing Windows on ARM devices and how you couldn't dual boot Linux and Windows on them. Odd that Microsoft would be talking about Linux.
