According to the semiconductor industry, maskless nanolithography is a flexible nanofabrication technique which suffers from low throughput. But now, engineers at the University of California at Berkeley have developed a new approach that involves 'flying' an array of plasmonic lenses just 20 nanometers above a rotating surface. With this approach, it is possible to increase throughput by several orders of magnitude. The 'flying head' they've created looks like the stylus on the arm of an old-fashioned LP turntable. With this technique, the researchers were able to create line patterns only 80 nanometers wide at speeds up to 12 meters per second. The lead researcher said that by using 'this plasmonic nanolithography, we will be able to make current microprocessors more than 10 times smaller, but far more powerful' and that 'it could lead to ultra-high density disks that can hold 10 to 100 times more data than today's disks.'

A Tablet stylus and/or a user's finger aren't the be-all and end-all when it comes to future data-input methods in which Microsoft is investing. There's also InkSeine, LucidTouch and Soap.
Xplore Technologies models use active stylus for navigation and data entry.
This graphics tablet is excellent for its primary purpose, and also has distinct ergonomic advantages as a more general input/navigation tool. It carries a hefty price tag, though.
Rather than opting to use a stylus to write, Handspring discovers that most users prefer to use a tiny keyboard to type data.
