Raymond Chen: In March 2007 , when PC World developed its list of the 10 worst PCs of all time, the top two slots caught my eye because we actually used both of them at work. Well, "used" is a strong term. Perhaps I should say that I witnessed these machines, as they spent the majority of their productive lives in a Microsoft employee's office.

The Mattel-branded Barbie PC ranked as second-worst in PC World's list. This computer was a vast improvement over those cheap computers in a boring color. Instead, it was a cheap computer in a boring color that you could dress up with pink stickers applied to the case, the monitor, the speakers�you get the idea. It also came with Barbie-themed software pre-installed.

We acquired one of as a test machine, and the poor tester who was stuck with this computer at least had the sense of humor to dive in with mock enthusiasm, applying all the enclosed stickers and decorations to ensure that the computer was installed "as designed." It was set on a table in clear view from the hallway and anybody who walked past and spotted the bright pink computing disaster was welcome to come on in and play with it.
