I used to run different computars with different OS'es, but then I got hit with an arrow in my knee...
Unclutter your life, use one main OS as workstation, keep the rest for hobby stuff.
Tried to fool myself many times to have multiple systems. Sorry Win 7 is the new AmigaOS, its fast, multitasks, boots instantly, many great apps, great GUI when you turn off the aero stuff and make it look like Win2000.
For sure, I do not run Win 7 on my server boxen (look I used the word Boxen, not box because I am a cool computer dood with l337 skillzorz in all major appz), on the Web boxen (LAMP-server for my clients to check out web boxen work boxen on) I am running Ubuntu Boxen edition.
On the Fileserver Boxen I, holding 18 TB Truecrypt storage boxen system Off course I dont run windows, Ubuntu server Boxen edition there too (with GUI, hey its 2011 and you can point n click in servers). So thats two computars that are boxing with Ubuntu and one computar for Win7.
As for Amiga, what more can be done in WB that have not been done in past 20 years, nothing, so my Amiga boxen only gets used when I need to use specific Amiga boxen stuff.
If you use a system for a specific Boxen use you dont end up with a cluttered Computer boxen environment, you do not really need 10 different boxen with different OS but if it makes you feel better, do not let me piss on your parade.
