The end of the PC revolution?

Terry Griffin writes "This leader in this week's Economist speculates that the PC revolution is nearing its end and will be followed by a revolution in PDAs and other specialized devices. Much of their argument is based on the unstability and therefore the unsuitability of today's PC for many tasks. I think they're right to conclude that these other devices are the wave of the future but not because of the unstable PC. As Slashdot readers know, a PC is perfectly stable if you put the right OS on it. "
