I don't find the need to hop between Windows apps and Apple apps. Just bought BidX, it works great! I've always been a Mac guy and cannot imagine going over to the dark side!
Gotta endorse hschol above; take your ID in when you buy. We get other discounts too on software, hardware, etc... just ask and the guys in MEM at the Apple store -- they know we're FedEx types and they're smart on what we get discounts on. I am pretty sure you only get the discount at the Apple store; you cannot go to MacMall or some other vendor and get the discount.
Hopefully, in a yr when my current cellphone contract runs out, there will be some deal where you can buy a MacBook and get a discount on an iPhone.
Just my 2 cents, get the extended warranty too.
