If you're tired of fumbling for the power button for your PC, or if you'd like to stash it somewhere out of sight, the Sharkoon PC Jump Start allows you to bring the power button to your desk via USB.
Not only does it let you move the power button, but it also gives you two additional USB ports, as well as a headphone and microphone jack. The perfect solution for remote access to a media PC or a useful desktop accessory.
Available from Sharkoon for 15 euros ($22). It's available online from many German retailers, but you'll have to do some hunting to find a US distributor.
