This thread brings up an interesting question.... Install base... What was it really in the last couple of generations? A lot of hardware dies and goes away only to be replaced by a new one yet "install base" would say that is two consoles. To answer the OP:
3 DS lites -- 3 family members...
3 PS2s over several years. Two died. Third one still works.
2 Sega Genesis systems. Roomate snagged my first one.
2 Game Boys (Advance and SP)
Everything else just one.... I've had my 360 and Wii both repaired once.
