Following our report earlier today on Best Buy stores planning to carry the Mac mini, several MacMinute readers note that they have already seen the low-cost computer at the retailer. “The Mac mini was available this weekend at my local Best Buy in northwest Ohio,” one reader said. “I work for Best Buy in San Luis Obispo, California, and we are already selling Mac minis,” another reader said. Others note that the Mac mini is available on Best Buy’s website — but it has been available online since late January.
