Personally, I think Machines have the best service overall compared to Macstudio and Epicentre. Especially when it comes to queuing up to buy iPad 2. The staff there makes sure those inside the queue only gets to buy iPad, for those who were initially inside the queue but got out just to walk around doesn't get to go in back and they have to queue from the back. They have good crowd control in this situation. Additionally, they don't force the customers to buy any cases or covers for the matter unlike Macstudio which forces the customers to purchase the Smart Cover if they want to get the iPad.
