Two weeks ago i bought my new Macbook Pro 15 inch, but is was even slower than my 2,5 year laptop pc. A real bummer, but thanks as alway to a communnity i got it solved. I noticed that my Ram memory was really low and the waiting icon just kept showing up.
Google and the community of Apple solved it, only some say it's temporary and comes back again. But for now, give it a try and maby it helps you to.
Even do it said it was ok, the repair still helped boosting my Macbook Pro with OS lion to normal speed.
