Portable computers used to be rare and expensive, but these days they make up almost half of all PC sales. In Western Europe, they represent well over half.

Businesses still buy a lot of desktop computers, but consumers now prefer notebooks, largely because prices have dropped precipitously, says Eszter Morvay, a senior research analyst for the global market intelligence firm International Data Corp., in Framingham, Mass.

So why did they take shortcuts? Maybe they didn’t realize that they were cutting any corners. Only when their code was deployed and exercised by a lot of users did its hidden flaws come to light. And maybe the developers were rushed. Time-to-market pressures would almost guarantee that their software will contain more bugs than it would otherwise.
