Say you've got an iPhone and a MacBook Pro (the MBP has Mail.app up and running and is set up for your MobileMe account just as the iPhone is). New email comes in to .Me and then gets pushed to both devices immediately (iPhone + MBP)? Or will it only go to one? It seems right now (and I know MobileMe is not fully functional yet) will only push to my iPhone if and only if Mail.app is NOT open on my MBP -- like it will only push from the cloud to a single device (and it prefers to push to my Mac) -- is this the way it is supposed to work? Or is this part of this rocky start we're all too familiar with?
