When the IBM PC turned 20 back in 2001, I said to myself, “Really? It’s that old already?” I was honestly surprised. Now that the PC platform is 30 (as it just turned today), that age seems obvious. (“Thirty, you say? Sounds about right.”)

Computer technology has come a long way since 1981, and the last 10 years in PC land have been just as eventful as the first 20. We’ve seen the Internet’s social explosion, juice-sipping Intel Atom processors, netbooks, powerful sub-$500 desktop PCs, the iPhone, the rise of the consumer tablet computer, and — oh yeah — Macs are more like IBM PCs than ever, living their lives in an x86 world. PCs aren’t necessarily beige metal desktop boxes anymore (as they still were in 2001) — in fact, folks are more likely to buy a thin laptop computer in 2011.

My point, I guess, is that I’m glad the IBM PC is 30. It is probably time to move away from the paradigm set in motion by the Wintel duopoly in the 1980s, although we may never fully escape it on the desktop. That is not necessarily a bad thing, but it’s time to try some new ideas in personal computing. And we are. With non-x86, non-Windows tablets and smartphones as influential as they are now, the winds of computing seem to be blowing 180 degrees away from the Intel-Microsoft PC platform. It’s exciting to think where those winds will take us in the future.
