You didn't read the article. It's for retail/commercial applications, not for consumer use.
As a developer, I've had to slum a few kiosk projects in Windows land over the past few years. Touchscreen support for OSX (Objective-C) has been practically nonexistent. Unfortunately, Windows 7/8 has really been the only choice.
If Sharp can put out a reliable commercial display with a solid OSX SDK for a reasonable price (sub $10K USD - remember, this isn't for your home computer), they will have a winner on their hands. Even without UIKit, I'd still kill to be able to develop multitouch Objective-C software (a la iOS) instead of Win 8 apps.
