Don't know if this counts...
Till recently we used a "real" Amiga/040 (with DPS PAR) for frame storage, all during the 90's it was our main graphics workstation. It has now been retired (sold) as we went completely digital. Like Aegis above we do keep de spirit of Amiga alive by using progs like lightwave, aura and elastic reality. The one thing we definitely miss is arexx, throw together a few lines of code et voila you just improved your workflow 200%. Nothing like that on our current machines.
Come back Amiga ... Come back stronger than ever...
