Mac is a niche market that only holds about 5% market share.

New numbers are out from market-research firm IDC and search-analysis firm comScore on October 13.
IDC’s data on worldwide personal computer shipments shows Apple coming on increasingly strong in the third quarter of 2010. While overall shipments were up 11 percent (3 percentage points lower than expectations, as TechFlash’s Todd Bishop notes), Apple bucked the trend. Apple’s U.S. share grew with 24 percent in the quarter, making Apple the No. 3 PC vendor here. That puts Apple just behind only HP and Dell in the U.S.
(As Bishop tweeted later, the new IDC numbers don’t include iPad sales, but IDC analysts said iPad demand helped drive up Apple’s PC shipments, seemingly via the halo effect.)
Update: As my colleague Larry Dignan notes, in worldwide shipments, according to IDC, Apple is not even in the top six, in terms of vendor market share , which means it has under 5 percent share.

As I think someone may have noted, Apple isn't in the business of having market share, they're in the business of making money, which they do very, very well, as you may have noted if you're tracked their stock lately. They're also number 1 in the USA in customer satisfaction.
And I wonder what the market share numbers would look like if you looked at it by the use it's being put to...e.g. housekeeping (internet, home stuff), music, image arts, business vs non-business, etc.
