I actually owned a Mac before buying an iPhone. I would have bought an iPhone when if first came out (which was before I bought my Mac, but was locked into a contract).
I've owned at least one Mac continuously since 1985 -- what is this iPhone of which you speak?
Actually, it's owning an iPod touch that makes me want an iPhone. Owning an iPhone will make me want an iPad, which may eventually make me want a Mac less.
Yes it did actually. Once i got my iPhone i wanted all of my electronics to be apple. I just love the apple interface, and the elegance of their devices.
Been a PC user my whole life, but when I got my first 3G, I fell in love with Apple's clean interface and went without DVDs and Voodoo BBQ for about a month to buy my 21inch iMac. My boyfriend still swears by his Windows, but I am a firm believer that once you go Mac you don't go back. Now we both own iPhone 4s and an iPad. Windows lover my butt.
