SAN FRANCISCO — After decades as the computer of choice for homes and businesses, the desktop PC is being pushed to the scrap heap by its smaller, nimbler sibling: the laptop.
They've been around since the early 1980s, but portable computers are finally taking over. Last year, for the first time, American consumers bought more of them than desktops. Sixteen of the 20 bestselling PCs on Amazon.com this holiday season were laptops.
U.S. corporations are expected to make laptops the majority of their computer purchases in 2008. BNSF Railway Co. already has. Of the 4,000 Dell Inc. computers it bought last year, 60 percent were laptops, so rail inspectors could file reports from their trucks and other employees could work from home.
"They were in a totally tethered world, and now they have no tethering at all," said Jeff Campbell, the Fort Worth, Texas, company's chief information officer.
Faster, cheaper technology is behind the most sweeping change the computer industry has seen in a generation. Buying a computer that can be spirited away in a briefcase or backpack no longer requires a big sacrifice in performance, storage or money.
