I used my first computer at age 3 (in 1996), a 33Mhz 486 with 8MB of RAM.
Oh God, you're making me feel old! I had been using PCs and various 8-bit machines up until then, and was introduced to the Amiga in 1995 - made the 486 DX2 I had been using feel like a total joke! Bought my first A1200 in '96 then, and that was it

I was born in 1981 and was programming an Acorn BBC Micro before you were even born!
Welcome along, and enjoy the A1000 - it's a lovely old machine! You just have to remember that it was incredible for the time but even an A1200 from '94 will run rings around it...
