Over at Mac Daily News, they're citing a USA Today article which indicates that Apple's "home computer market share" hit 7.6% in May 2007, up from 3.2% in May 2004. MDN says "we assume that the market share number came from USA Today research." Presumably this number is for the US and obviously focuses on consumers rather than businesses, but this feels right to me. We've already mentioned that sales are way up and Mac shipments are up 30%. Let the Mac train roll on!
