I had a lot of fun on a friend's 1000, but still don't think I would bother buying one now. I like the case, and love the keyboard, but I can't really see the point of having one today, other than for nostalgia. Unfortunately, nostalgia doesn't pay the rent.
My friend used to write his assignments on a 1000, sitting in an armchair some meters away from the comp, with an extra long keyboard cable, and the keyboard on his lap. I can't remember which word processor he used, but it had the option of different background and text colours, and a good zoom function. The guy is dyslexic, so it was just perfect for him to tune the colours to suit his vision difficulties, and be able to relax in an armchair while writing. I don't think any other computer offered that, at that time. I thought it was really cool.
We also used to watch Robotech cartoons on his monitor, which, as a Mac user, I thought was just damned cool.
