A BoyGeniusReport claims that Apple promised new laptops to bands performing at a holiday event reportedly hosted by Apple:
Apple had a recent holiday event where they had artists perform (some really big names, too), and they all did it for free! Why did they perform without being paid? Apple promised to give every performer and band member once of the new laptops they are coming out with at MacWorld! Thats all, folks!
The sources of this report are questionable at best, and are not likely in a position of knowing what products are being revealed at Macworld.
