Apple seems to think you need an appointment for more "customer service" at their stores now.
I just bought one without an appointment. However, they are not set up in the Apple stores yet. The sales person had to go in the back to get a demo for me to try out. It also took some convincing on my part to see it. They said all the new models will be out for viewing on Thursday.
I asked the guy how to get iwork from my imac to new macbook and he said to use my firewire port. NOT kidding! Then he caught him self and said, oh that model does not have that. You can use your ethernet connetion. I am not the most computer savy, but this all seemed to rediculous.
They still got my money though. Love every apple product i have bought. imac & iphone 3g.
