Oh yeah, wireless is so easy on the Mac, until it stops working, and it says your connected to the internet, but you really aren't and you can't use the almost $3000 MBP to do anything on the internet. Then you call apple care and they tell you to buy an apple router, even though your newer Linksys router has been working 100% with two other newer intel macs and two PC's. Then they tell you that there is nothing they can do for you..........Can you see where this is going? Sorry I am just frustrated.
In all seriousness my mac was great with wireless until my problems started, and I know lots of people who had no problems and still have none. You should be fine. Pray that you don't have a lemon like ME!
