Hey I remember seeing a mac website where it would tell you the exact time since the last imac/macbook/ipod update..and tell you if you should wait or go ahead and buy now. Its hard to explain but do any of you guys remember what it is called? so i can check it out. As im lookin to buy a macbook... will wait till oct for new OS...but want to know when next technical changes will take place. Cheers!
