All computers lock up or crash, and no operating system is immune (as a matter of fact, we crashed once as we wrote this answer), but singling out specific reasons oversimplifies the issue, explains Daniel Jackson, a computer science professor at the Massachusetts Institute of Technology. The underlying cause, Jackson says, is that hardware and software developers are trying to bring products to market in "Internet time"-that is, hyperfast. The result: Quality and reliability suffer.
