I spent a lot of time and a lot of money there way back when, including lots of company money. It was a fun place to go for a while especially if you are a tech nerd/geek type. The degeneration started much longer than 5 years ago. Their business practices were the source of a lot of controversy and I believe lawsuits if I remember correctly. They were infamous for putting returned stock back on the shelves (as new) without even checking it out to make sure it was good. Lots of people got screwed over. They got me one time many years ago and after that I never went back. By then other sources were coming up including the internet.
In its heyday the one in Orange County was really something. You had to get there early just to get a parking spot and go buy something, and the lines would snake around for miles, especially in the holiday season.
