Weird Al didn't write that, he wrote "It's All About The Pentiums" which is what OP is riffing on

They based it on these two phrases:

I beta tested every operating system
Gave props to some, and others? I dissed'em

And

You say you've had your desktop for over a week?
Throw that junk away, man, it's an antique!

Along with the chorus line "It's all about the Pentiums, baby"

Also, the rhythm of the Weird Al song is fine, it's worth watching even if a lot of it is pretty dated since it's thirty years old now
