Rumor: Cheaper Macs soon
There's a thin rumor at AppleInsider suggesting that Apple will introduce less expensive MacBooks and iMacs this spring. Unfortunately, the article doesn't mention pricing or what concessions will be made to reduce the cost.
While it's easy to assume that Apple is reponding to the Microsoft ads that depict their machines as too expensive, AppleInsider's source suggests that the price reduction is a response to the popularity of netbooks (Acer has been showing growth).
Apple typically starts the back-to-school sales at towards the end of the summer, and has bundled an iPod with computers sold to students. That offer plus a low-cost Mac would be powerful.
