Ummmm... Because nobody uses it... Only about 25,000,000 nobodies...
Last quarter Apple's market share topped 6.6% of all personal computers shipped.
>>> bogus numbers, the 6.6% number? To be in eighth place behind Gateway doesn't sound promising either<<<

Apple Worldwide Market Share Inches to 2.5 Percent
"...The worldwide Q2 results put Apple in eighth place behind the likes of Dell, HP and Gateway.
[worldwide]...Apple's 2.5 percent share in calendar Q2 is also a slight increase over the 2.3 percent share it had in the first quarter of this year....
[US] ..IDC has adjusted Apple's Q2 U.S. market-share, lowering it slightly to 4.4 percent, TMO has learned.."

It appears from your inaccurate numbers that aside from no threat from virus writers, Apple's number crunching potential/usefulness is also equally limited.
Then again this sentence may say it all "Much of Apple growth was spurred by help from sales of the iPod digital media device..."
Apple users probably never have problems cuz they really never actually sign on to the web, they only powerup to look at photos of themselves while listening to their iPod given this headline "Apple Unveils Photo Software for Pros"...
