Mark started at 11 with a Apple... My first experience was a Sinclair ZX81, however my first programming was on an Apple II (not e, not plus, just the II)... I wrote a math quiz program for my 4th grade class (or was it 3rd grade)... I remember my number one bug with that program - I was generating random numbers and one of the quizes was division, so every once in a while I would get a divide by zero. I can't remember if I fixed it or not, but I remember being really stumped on how to solve it... I guess that's what you get for coding at 9 or 10  ;-)
