I just got a new imac about 6 weeks ago. So I am totally new to mac and it's communities. It seems like you could really go crazy trying to make sure you have the latest update at all times. If my PC was going to die, and I would have to buy a new one, why wouldn't I buy a macbook now if thats what I wanted and needed. Because right after this macbook is released, if it's not aluminum or ultra slim, there will be speculation surrounding that update. And the next and the next...
I need a small laptop with great battery life. I really like my imac so I'm going to go to the store tonight or tomorrow and grab a new macbook. If you spend your whole life waiting, you never get the joy of owning.
