Photos: Holiday tech gifts we don't recommend

6. Anything with the "Digg crack code" on it

This past spring, social news site Digg soared to the top of mainstream news when the company refused to obey a Digital Millennium Copyright Act (DMCA) takedown notice concerning an HD DVD crack code that a member had posted on the user-powered news rankings. As a result, the "forbidden" code became the geek slogan du jour to toss on mouse pads, coffee mugs, boxer shorts, and just about anything else you can make on CafePress or Zazzle. Also getting in on the trend were tech-focused retailers like Think Geek, which still sells this T-shirt.

But we don't recommend that you give any "Digg crack code" gear as presents this holiday season. First of all, only the most uber-tuned-in of tech enthusiasts would even understand this in the first place. And second, even if they did, their reactions would probably be something along the lines of, "That is so last year." You'd be better off with "All Your Base Are Belong To Us," which at least has some retro-chic appeal now.
