I'm a sucker for a good analogy. I mean, I am a writer after all. That's why I dig Dawn Blair's blog post that compares a digital artist's computer to another artist's brush, chisel or pottery wheel. It's an essential tool. The post reviews CheckIt Diagnostics from a digital artist's perspective.
"So many programs have been dedicated to checking for malware, viruses, rootkits, registry cleaners, etc. that it's nice to find a program that cares about the hardware side of the computer equation too."
