Hi there. This is going to be my (unfortunately) first time taking my powerbook to the Apple Store. It seems to be suffering from a ridiculously-slow airport connection, and I suspect that there might be something wrong inside. The Apple Store near my house is now closed, so I plan on going tomorrow mornng. But if I try to get there as early as possible (opens at 11:00 AM), do I still have to make a Genius Bar reservation before I go? Or can I just show up (since I am bringing my powerbook along too)? Sorry, it's just that I've had no experience whatsoever with the Genius Bar system Thanks for any replies!
