Today, we learned that AppleTV doesn't come with cables to connect it to your TV or Stereo. Before you go and get yourself ripped off buying cables (on top of paying premiums for the AppleTV itself), I thought I'd remind you of some good HDMI, Component, and TOSLink Optical Audio cables that can save you up to 95% compared to Best Buy's gold plated crap.
Apple's gear is pricey, and depending on the person, it's worth it or it isn't. (That's for you to decide.)
But as far as cables go, there's a lot of stuff that works for a fraction of the cost that the big boys are trying to screw you for. You're not just limited to firefold.com, either. Monoprice.com has some good stuff, too. The point is, don't fall for Best Buy or Monster Cable's ridiculous pricing.
