From this c/net article:
Acer president Jim Wong said touch-screen laptops will eventually dominate the PC market, although he also warned that Windows 8 may take a while to win over computer users.
In October of 2010, Steve Jobs said that Apple had done "tons of user testing on this, and it turns out it doesn't work. Touch surfaces don't want to be vertical," referring to touch on laptops. And so far that philosophy appears to be intact at Apple, none of whose computer products -- as opposed to its iPhones, iPads and iPods -- feature touch screens.
Wong also had a lot to say about Windows 8, starting with the fact that it isn't likely to be an immediate hit.
Windows 8 is a "new system that consumers must learn and the learning process will prevent the operating system from taking off quickly," he said. Wong, however, argued that criticism of the touch interface has been unfair.
