Toshiba offering tablets with a 3D display definitely seems like a possibility now. The evidence pointing towards this includes the fact that Toshiba has already expressed interest to the lenticular lens-based panels that the Taiwan based company AU Optronics or AUO has come up with. The panels allow for a nice 3D viewing experience without having to wear special 3D glasses. The panels though are a bit pricey and though Toshiba has firmed up plans to use such panels to make its new range of 3D enabled notebooks, there already are reports of some tablet manufacturers also having shown interest in using the same panels to make tablet PCs.
So what this means is that 3D enabled tablet PCs might well be the next big revolution in the tablet PC segment with a 3D Thrive tablet perhaps leading from the front.
Right now, the only tablet that boasts of a 3D display is the G-Slate from LG.
