I'll be 30 in a few months.
I saw an A1000 running Deluxe Music Construction Set sometime in 1989 and I knew right then and there that I had to have an Amiga. Of course, I was 12 at the time, so I had to make do with my C64. I bought a green 880K floppy with my allowance money as a consolation, even though I couldn't do anything with it.
In 1990 my dad got me a 2nd-hand A1000. Being in so late in the game, and living in the USA, of course it was difficult to get any software, but I finally used my green floppy to store some Deluxe Paint pictures and documents written with Scribble. I was in heaven.
I pre-ordered the A1200 by four months, so I had one of the first A1200's in New England. It's still my favorite computer of all time, but I remember how disappointed I was in the performance with the 020 and AGA chipset, even with the fast RAM card I added later. If only the fabled A1000+ had been released!
I couldn't get much software for my A1200, so I made my own. Pinball Illusions was the last game I managed to buy in a store, which oddly was also the first "real" AGA game I owned. I remember arguing passionately about the merits of the Amiga, and how much PC users rolled their eyes.
Ah, well. I still got my money's worth out of the machine, along with a passion for proper UI design.
I mostly use WinUAE now. I use my A1200 maybe once a month to play DuneII, which doesn't run correctly under emulation.
