Zero. Phone -- I don't have a smart phone Desktop -- I prefer to build my own computers since it's far cheaper. The fact that I run linux is even less incentive to buy Apple. Laptop -- I have a Lenovo Thinkpad that I love and was quite inexpensive. Tablet -- I have a Kindle Fire that I primarily use when travelling. It's no iPad but cost a fraction of the price. I just don't see the appeal, but then again, I'm not the target audience (grad student with limited disposable income and no desire to use Apple's OS).
