I did...and still do! I had an Atari 2600 gaming system for a few years, which I sold to buy a Commodore PET 2001 (8K RAM, on-board cassette). I sold that and got an Atari 800, which I still have and it still works, believe it or not. In fact, I had the thing powered up and running as recently as 6 months ago.
It was a great computer; far better graphics than the competing Apple II series and at a lower price. Eventually I upgraded it to have 48K of RAM, two floppy disk drives and an 80-column card. I sold it to a friend, used the money to buy my Amiga 2000 and eventually bought the Atari back from the guy I sold it to. That was 15 years ago and, as I said, it continues to work to this day alongside my original A2000.
One of the main reasons I bought the Amiga was because I knew Jay Miner had gone to Commodore from Atari and a lot of the custom chips in both systems were designed by him.
