Hello All, I'm new to this site. I have been waiting for the release of the new OS to buy my first iMac. Does anyone know when iMacs ordered from the Apple Store will ship with SL installed (rather than buying an iMac and upgrading it)? Also, any compelling reason to wait on an iMac purchase now that SL is available? I plan on buying a 20" iMac for my wife as her email/web/photo machine. She doesn't play games or do anything to intensive with it. The 24" iMac is too big for her desk. Thanks for the help!
