On the complexity of personal computers

If you believe that software made for a mass market audience that costs $129 (or even $259), does just about anything you want the instant you specify, and runs on mass-produced hardware that fits comfortably in a small backpack will always perform flawlessly, you’re deluded. If you believe any advertising or marketing to the contrary, you’re twice deluded, once by yourself and once by someone else. You want 100% reliability for cheap? Buy a calculator. But don’t expect anything more than arithmetic.
