Oh, I started quite late with 18. After graduating from art school ;-)
I started programming in Java on a crapy old computer. I found it in the cellar. No USB, only floppy disk. And no, it was not the time that floppy disks were still state of the art.
When I wrote the first java program (a hello world), it took (and I am not kidding) 30 minutes on that computer to compile. So, I knew I had to put all my savings into a new machine. That was then a laptop from a discounter (Yeah, I was new to the whole thing, and it seemed like a reasonable idea, back then).
