16, started when I was 5 or 6 with an Apple II (I recall pushing it off the desk, whether or not this memory is truth is something I don't know), afterwards we got a bunch of PCs from Intel since my dad worked there. My dad built a PC from the ground up when I was 8, so most of what I know about hardware is from him. When I was 10 or 11 I got a PC of my own (an eMachine) along with a copy of Mandrake 6.5 (Linux). Screwed up the PC pretty badly trying to install it, so I stuck with Windows at the time. A couple years later I got a Dell, gave my eMachine to charity, and so on and so forth.
A few PCs later and here I am now.
