1% market share worldwide. I was just recently in Vietnam, unsurprisingly I didn't see a single Apple computer, and most of the computers were running Windows XP.

Apple has around 10% [0] of the market for laptop sales (most consumer computers are now laptops, I don't know any non-enthusiasts who have bought a PC in the last 5 years).

Now, factor in that those sales figures include less developed countries as well as developed countries, and you're probably look at at a decent margin about 10% of personal computer sales for home use as Apple products.
