Does anybody know how the Aperture 3 trial tracks that it's been used. The reason I ask, I kinda want to play with it now, but I also want to be able to try it once I get my next MBP, whenever Apple decides to give us some Arrandale love. I'll probably migrate my user account over, so if it ties it to that somewhere I guess I better wait, but if it's in the system file I should be able to try it on my current machine and then again when I get my new one right? Anybody know how it works?
