Hi everyone. I have an iMac currently running 10.4.11 (Tiger). I chose not to upgrade to Leopard, because I didn't think it was necessary. I put off Upgrading to Snow Leopard because I would have to pay $129 for the box set to do an install. Now I'm pondering if mac will be selling the install disks for Lion or if it will just be upgrades only. My other question is, should i just install snow leopard and think about lion later?
