One of the more interesting  as it is not a from a technical publication is the article in which Business Week declares desktops dead.

"Some argue that PCs have become so cheap it doesn't matter that they're largely wasted. But that's silly. Sticking a capital asset worth $1,000 or so on every desk in a company -- and then replacing it every few years -- is no trivial expense. It becomes even less trivial when you factor in the considerable labor and other costs that go into maintaining and updating fleets of workstations and all the software that runs on them.

'RIDICULOUS DEVICE.' Then there's the fact that PCs often represent the biggest security hole in today's companies, a gateway for the evil-minded hacker and a repository of ready evidence for the litigious. It's getting harder to look at a business PC and not see an anachronism waiting to happen."
