"2. 3 Dimensional screens
The interface which is one of the big reasons keeping people from
linux (although not recognized for that by many people) will be
replaced by a 3D interface in the future. There is already
technology making it possible to show 3 dimensional images without
goggles, the only problem is you have to be right in front of these
screens. Using a personal device like a umpc your in front of the
screen already, so if the technology becomes cheap enough and
someone builds a usable interface, it will probably find wide
adoption quickly.
The great thing is that with Linux it's easy to create a
different interface, because that's not an integral part of the
OS."
