Most devices that you can buy for under $400 now run on ARM chips (frequently Mediatek). We're talking tablets (with keyboards), convertibles, even outright laptops (i.e. "netbooks"). These things qualify as computers. They are replacing traditional laptops, just as those replaced desktops.
And they do not run Linux out of the box.
