The mobile Internet to date hasn't been all that impressive. Phone screens are generally too small to carry a readable web page, download times pre-3G were appalling and now everyone has 3G in their phone no-one actually uses it.
Comes the solution from South Korea - a miniaturised projector (Korean Times) that allows very small devices (such as mobile phones) to project images onto any surface. Mobile phones already come with web browsers. Soon they'll be able to simply project a workable "virtual screen" onto just about anything. That's when the mobile Internet begins to get interesting.
Update: that's assuming mobile phone batteries are up to running a projector on top of all the things they do already, of course. And I think the short answer to that is that they're not. Hmmm. So why does Iljin (the company in question) think it's onto a winner?
