Incidentally, that 975,000 figure for Apple's sales is only 60.1% of their worldwide sales of 1.61 Million. I don't see a US market share of 2.5% on there, do you? In fact, Apple holds 2.8% worldwide market share using Apple's stated 1.61 million Macs (Apple's fiscal Q4, calendar Q3) and IDC's 57.052 million total worldwide PC shipment 3Q numbers. IDC and Gartner's numbers vary slightly due to differing methodologies.
As I mentioned earlier, Apple's worldwide market share topped 3% in January... also according to IDC.
