I'm aware I can call Apple to find this out, but I'm at work and figured someone would know. Furthermore, lets say it does come with Lion, is the F4 key graphic going to stay the same? Or would it be changed to match that of the Macbook Air? Just curious ... I don't mind Snow Leopard at all, but if I'm going to be forced to use Lion I'd at least want the function keys mapped properly (both internally and externally ) Edit: Nevermind, seems this question has been asked and answered. For those wondering yes, the F4 key has been changed to Launchpad from Expose.
