Aha. I understand where you are coming from. I was thinking I had to make most posts to qualify or something.
They just caught me out with upgrades. I upgraded my iMac and MacPro and my wife's MacBookAir to Lion then said OK to move all my data to the cloud from the iDisk. Then when I tried to upgrade my MacBookPro I got a message saying it can't be updated to Lion so now I can't have all my data automatically synched between the MacBookPro and the other Macs.
