Anyone figure out how to connect an Apple Thunderbolt Display to a computer with DisplayPort or Mini DisplayPort? (or a computer with anything besides Thunderbolt?) Bought a Thunderbolt Display a while back and my wife thought she'd be able to use it with her work PC laptop... but I haven't been successful in getting it to work. I think its an HP EliteBook 840. She's ready to kill me. Has an adapter been created for this yet or am I hosed?
