Apple's annual developer conference in San Francisco.
Windows 7 Multi-touch Demoed at All Things Digital
Microsoft has adapted the multi-touch technology of their Surface computer into Windows.
iPhone users will be familiar with the photo manipulation shown, but according to Microsoft, multi-touch will be "built throughout the OS". Other notes from the talk report that "Microsoft is re-thinking the whole user interface to better accommodate multi-touch for day to day use." Windows 7 is expected in early 2010.
Of course, Apple first introduced the use of multi-touch into the iPhone and has since integrated basic multi-touch into the MacBook Pro and MacBook Air's trackpad. Meanwhile, patent applications have revealed that Apple is working on more advanced multi-touch integration into Mac OS X. When asked by Mossberg if Apple had a jump on this technology, Ballmer simply responded (Engadget's notes):
There's a lot in Windows 7, and our goal's got to be, with our hardware partners, to produce fantastic PCs. ... We'll sell 270m PCs a year, and Apple will sell 10m. Apple is fantastically successful, and so are we.
