I think mouth to mouth marketing is doing a pretty good job. If I got a euro for every Apple product I helped selling I would be rich now
Apple's userbase is very loyal and fanboyish, like me. But I always stay objective and compare Apple products to other products like the Zune, or the Zen and give objective points why an Apple product should fit one better then the competor.
Last I promoted the MacBook Pro's as a good solution for my school here in Holland. They bought over 30 thanks to my advice.
They also bought 4 airport extremes.
And 5 iMacs.
My friend got an iPod thanks to me.
Another got a MacBook Pro (Penryn).
My mothers friend has bought an iMac thanks to me.
My mother is going to buy an Apple TV when the price goes down like it has in the US.
My brother is buying one too for movies on his 37 incher.
Girlfriend bought an iPod thanks to me, and her sisters (3) too.
Can I get credit Apple
? Nah I just love your products and therefore promote them!
