I hope something really interesting will be unveiled with Windows 10...
Another sticking point is the touch version of Microsoft Office. Any Surface ARM-based unit should have Office RT, though MS diluted that application suite's value on the Surface line since they released earlier to other platforms. I would hope a future Office RT is more robust in features than non-Windows offerings as well.
(There's eBay too, but... Kind of understandably scary.)
