You may know this person. She's got a huge flat screen TV. She's got a PS3 and an Xbox 360 and a Wii. She's got an iPad 2 and a Macbook Air and a Linux box. She's got a projector and a Kindle Fire and a delightful sound system. She's got a great DSLR camera, a micro four-thirds workaday camera, and a little Canon she carries around for snapshots. Wracking your brain to find some kind of gadget for this person, you would be forgiven if you gave up and resorted to a large stuffed wombat and a Snuggie.
But don't give up! I have the perfect gift for the gadget obsessed that turns their gift-receiving weakness (having everything) into a strength. Buy them HDMI cables. Think about this way: the more stuff you have, the more stuff you need to connect, and that means you need more cables. You can really never have too many. What kind should you get? Our friends at The Wirecutter, which aims to only recommend a single good product in a category, recommend the Monoprice cables that cost a mere $8. So, you could pick up three of them for less than the price of a decent iPad case.
