At first I thought this was a joke, but I took a look at the article. Good article by the way, as always. I got a idea, lets see if PC Doctor can fix problems!
If it can't fix that, its not worthy. Haha, because thats about the worst mistake a Linux user could make. (Personally, no one could make that mistake hahaha) Alright I'm done making fun of pc doctor. In a way, it does look useful, but not for 400$, I agree with you guys. Thats way too much money for a diagnostic cd and a few adapters.
