Apple has just launched its annual Black Friday online sale, and, as you may expect, there isn't a whole lot to write home about. The company has slashed the prices of its MacBook Air, MacBook Pro and iMac by a modest $100 for this year's 24-hour event, with the iPad 2 seeing a $41 reduction, and the iPod Touch getting slashed by a measly $21. Not exactly the kind of discounts you'd wait an entire year for, but they're there at the source link, nonetheless. For more tryptophan-laced deals, check out our ongoing Black Friday roundup.
