Why the classic desktop?

Why do people who need to get real work done insist on the classic desktop metaphor? This Slashdot commenter I think said it best.

iOS has been very successful among non-technical users because it simplifies things a lot more than a standard W.I.M.P. design โ€“ but once you get beyond casual use and into doing real work, multitasking becomes a necessity, and there is still nothing better than a "classic desktop" for that.

Slashdot has also recently suffered a crippling re-design, so there is no way any longer to link directly to a comment (which is typical of modern design bullshit), but itโ€™s part of this story.

But what the commenter said is exactly correct โ€“ once you need to look at or access more than one thing at a time (and donโ€™t get started with the completely asinine โ€œmulti-tasking is impossible!โ€ spiel that has nothing to do with workflow) to get real work done, using a Fisher Price โ€œMy First YouTube Videoโ€ interface just doesnโ€™t cut it.

Funny that Slashdot has also gone down the road of terrible, unusable UI design right around this story appeared on its front page.
