Apple's Back to the Mac event has kicked off with the bold claim that "1 in 5 PCs is a Mac". It's a staggering boast, and one that the Cupertino company makes even though the market has seen a decline over the last year.

It now owns around 20.7 per cent of the computer market, and has benefited from 23 per cent year on year growth (the PC market has only shown 11 per cent growth in comparison). It also claims that, contrary to popular thinking, the Mac still makes up for 33 per cent of Apple's revenue.

Additionally, the manufacturer has stated that of all the Macs sold in Apple Stores worldwide in 2010, around 50 per cent of them have been sold to new buyers. That is to say that they have been bought by people who have never owned an Apple Macintosh computer before.

And seeing as Apple sold 13.7 million Macs in the year, that means that there's now almost 7 million new owners out there.

Naturally, the iPhone's help in driving this rise in Apple fanboys is undisputed, but even still, it's a figure that may get Microsoft a little jumpy...
