I have a 1200XL in my collection (signed on the bottom by one of its hardware designers!). Compared to the 800XL, 600XL, 800 and 400, which I also have, it does indeed have the nicest keyboard. Since I wasn't following the Atari market closely in early 80s, I was interested to learn from the article that the 1200XL was announced and shipped before the 800XL and 600XL and then quickly discontinued.
