There just isn't that many people who want to run Linux on their computers.
Yes there is. I know lots of people who run Linux on their desktop. And I bet there's probably even more people that would be interested in a Linux tablet. The argument that Linux is this totally obscure precious little snowflake just doesn't work anymore.
For varying definitions of "totally", "obscure" and "sucking". In my opinion, Mac and Windows "suck" compared to my Linux desktop, but I'm not going to assert that as fact.
1-2% of a global desktop computing market is small in percentage, but ENORMOUS in total numbers. We're talking about many, many millions of users. And that's just desktop. The potential size of a Linux tablet market is really quite big.
But none of that matters if Linux enthusiasts only want to buy a Windows tablet, and reformat it with a free version of Linux that barely works on that hardware.
