I use a mid-07 original alum. 20 inch iMac with VLC Player and the Apple Remote that came with it. I've also used the remote a ton with iTunes and playing DVDs. I just think it's notable that the original battery that came with the remote still works. Granted I've had a low battery signal show up periodically on the iMac for awhile but I've never changed it. I'm so attached to this remote that I'll probably end up getting a Mac Mini when I get something new. There's nothing like buttons and not having to load anything. I'm amazed at how well it works with VLC Player.
