The Desktop PC Is *NEVER* Going Away. Period.
I don't know why the electronics industry as a whole is in such a rush to declare the desktop PC dead. You could of course make the first assumption that they want to sell more handheld gadgets to fill the void, but really they make money from selling PCs too, you know. The PC made the computing industry what it is today.
(By the way, a note to Apple-ites: YEEEEEEEESSSSSSS I include "Macs" when I say "desktop PC!" Is it a computer? Is it your personal property? Is it on your desk? Then it's a desktop PC. Even if it's from Mars. Moving right along...)
Just recently it's BIOS, a standard PC firmware interface going bye-bye - of course, that's declared so by the company that wants you to replace it with what they're offering. A short while ago it was no less than Google insisting that desktop PCs will go away in three short years. For that matter, you can't swing a mouse without hitting another article about the death of the PC.
