My first computer? A ZX81 (with patented "wobbly" ram pack and thermal printer). the '81 was basically an overgrown calculator with ideas above it's station, but it did teach me programming (started with 10 PRINT "STUART", 20 GOTO 10

) , and it did have one of the most scary games ever (3d monster maze).
Then, I had a spectrum 48k (with the bad colour clash problem and the rubber keys). The speccy had faults, but you could get some interesting effects to display using the "Border" command, and it did have some addictive games (specially Manic Miner, Jet Set Willy and Sabre Wulf).
Then I had a commodore 64. This was an amazing computer for the time. Some very addictive games (Monty on the Run, Thing on a Spring, Parallax, Bounty Bob Strikes back)
Then onto the Amigas. I had a 500 (with 1 Meg ram) and then a 1200 (with 120 Meg HDD). These were, and still are, my favourite computers.
Since then I have had a variety of PCs and Macs, culminating in the Athlon 64 tower PC, Piii700 server and Sony Vaio laptop I have now. While these are all an order of magnitude more powerful than the Amigas, the amiga still had a pioneering spirit that the PC lacks, and windows has always seemed to be a cheap copy of Workbench (the Amiga UI) even though it is more powerful.
