This can't be good for anyone but Apple—a patent app filed in 2004 has been granted for their capacitive multitouch display. UPDATE

Apple's touchscreen is still the best in the entire smartphone market, and while the implications of this patent are still unclear, it's certainly hard to imagine it helping any other companies close that gap. [freepatentsonline via Engadget]
