OP - They'll activate in store, but you won't be able to use it with your computer without updating. Just buy the $29.00 SL disc they sell in the store and you'll be fine.
I would but it's a PPC G4 chip which won't allow me to upgrade. But at least I can use a new iPhone until I update to an iMac, just deciding which one to get.
Can't you get Leopard then? I'm pretty sure you can install iTunes 9 on Leopard.
What's the point if he's getting a new iMac?
