Well, I used to use my A500 for testing software that I wanted to run on 68000/ECS. (i'd program it on my A4000 68060, Mediator etc. etc.), but now its in my parents loft with my spare-parts A1200, and my A600.
In my flat I have my A4000 (which is in daily use as my main computer), and my A1500 (which is used to run things that require Paula audio; sadly my A4000's built in sound is dead), and playing old games. The 1500 has a GVP G-Force 030, SCSI hard disk, network card, and GVP IO Extender.
