Here's the article, but I'll save you a lot of click-throughs and post the winners below. Some are very, very funny.

Steve Ballamer sells Windows 1.0

Don't copy that floppy

The Ellen Feis Apple switch ad

Keeping up with Commodore

MS DOS 5 Upgrade promo video

Movie piracy is a crime (apparently they included this one because the only place you can see it is on a legally purchased DVD)

Atari Pole Position

BT Slimtel

Kevin Costner flogs Apple kit

Amstrad Studio 100

Of course, none of this is as painful as the law firm anthem.
