Mini Displayport monitor as your daily? That's all fine and dandy, but what happens when your desolate friends come over with machines that only tote DVI? That's where an adapter like Kanex's C247DL comes in. But unlike other adapters we've spied before, the company's latest is dual-link, allowing you get your groove on with displays that boast resolutions greater than 1920 x 1200. It also sports a USB port, giving you full control of say, we dunno, the speakers and iSight camera of Apple's 27-inch Cinema Display? At $149 it isn't cheap, but can you really put a price on friendship?
