May be time to Upgrade

I am a Mac user and have been using the 22″ iMac for several years, but I think it might be time to upgrade the operating system. The problem for me is that I want to run the new iLife suite and it requires Mac OSX version 10.6.3 Snow Leopard. I have it on my MacBook and I love it so I guess I will have to take the leap and upgrade my iMac. Should be fun.
