Last Gadget Standing Nominee: Kanex XD
Price: $149.95
The Kanex XD does one thing and while it’s probably something that shouldn’t need doing in 
the first place, it does it well. It transforms your 27-inch Apple iMac or Apple LED Cinema Display into a High Definition display. This allows you to connect and play your HD devices: Blu-Ray DVD player, PlayStation 3, Xbox 360, or digital set top box in HD format. Reviewers have noted that Apple’s limit of 720 dpi 720p on the screen (no fault of Kanex) is an issue. But, they’ve also noted that Kanex provides a true, crisp, and clear picture from any HD source with no video scaling. To sweeten the deal, full control of volumn and brightness is available through the unit’s Bluetooth keyboard, and the XD also supports audio pass-through to enhance sound as well as video.
