Remember those distortion issues people (like me) were having with the unibody MacBook Pros while using the Mini DisplayPort Dual-Link DVI adapter? We can confirm that they're still there in the new machines.
The discussion thread reports that Apple recommends updating the firmware in the adaptor itself to 1.02. Unfortunately you can't update it at home, so you'll have to go to an Apple store to trade it in. Even more unfortunate is the fact that users are saying the 1.02 firmware makes things even WORSE.
