Who hasn't dreamed of enjoying 3D movies without fumbling for an annoying pair of glasses? This year has seen glasses-free 3D tech — most notably the Nintendo 3DS and a Toshiba Qosmio glasses-free laptop — but there are still challenges. Viewing angles are a big concern: anyone who's used a Nintendo 3DS knows how perfectly you have to hold your head in place. Large-screen implementation is also a challenge: the larger the screen, the harder the 3D experience is to replicate. The Toshiba Qosmio pulled it off on a 15-inch screen, but we still have a ways to go before hitting a living-room home-theatre size.
