Has there been any merit to the claims that a visit to the Genius bar will send your MBP back to you with a stiffer lid? I understand that there are countless mentions on this board about the issue, but I just want to know if there's any kind of resolution or "fix" for this. I absolutely adore my new MBP, coming from a Penryn. The only thing I hate is the loose hinges. It's almost embarrassing when someone else is using your machine and they comment on how annoying or flimsy the lid feels.
