This article discusses PC reliability, one of the most pressing issues regarding computers. Nearly a quarter century after the introduction of the first IBM PC and the outset of the personal computer revolution, PCs have largely become commodities, with little differentiating one brand from another in terms of capability and performance. Most of today's software is similarly mature, having gone through many upgrades, with less opportunity for the introduction of groundbreaking capabilities. These days, what most differentiates one computer product from another is reliability--the hassle factor. The PC industry may be maturing, but computer products are still very much prone to glitches, bugs, security vulnerabilities, incompatibilities, premature failure and other problems.
