Pardon my ignorance....
I work for a Printer and Ink company with a two letter name that moonlights in client PCs. We chucked the deadweight (and our server business along with her) that was hell-bent in running our company into the ground with shitty products a few years ago, so I'm kind of wondering, why is it called a ruler? Something to do with the form factor or the size of the disks? I'm genuinely curious.
