yup, another 'me too!' to the list..
bloody annoying since I forked out for a new MBP, was so excited to get it so I could finally get some good work done (photoshop and design stuff), to start seeing these lines.
Didn't know that closing the lid and opening it again fixed it, I just put up with it until I couldn't look at it anymore, then went away for an hour and came back. Also just read the control-shift-eject key combo. Not had chance to try that yet, but I saw what it did, and everyone else says it fixes it. Preferably, I'd like Apple to fix it for good!
IMO, the amount of dodgy screens I've seen from Apple is a bit disheartening. Not only with MBPs, but most of them. The hardware rocks, the OS rocks, the screens/monitors kinda let things down a bit.
