I am switching to Mac from being a Windows user for the past 10 years. I can't wait to get back to using a Mac. I am very excited to purchase my iMac, but I am wondering if anyone knows when they will be shipping with Leopard pre-installed? I know I can get my iMac now with Tiger, but since I am new to all this, I don't want to have to explore two different OS'. I was surprised and a little dissapointed that the computers themselves don't ship on the day of launch with Leopard, but I'd like to know how long I will have to wait. Thanks!
