I love it as a pure hobby. I work on monster machines all day (like my $7000 Voodoo laptop, building websites, doing 3 D animation and such). To me, the few hours a night working and learning the Amiga is just plain fun. Half the fun is hunting down parts, collecting the pieces and so forth.The fact I have a few hundred floppies to go through and figure out what they are, and if they work is half the fun.
I have a buddy who restores old cars, and he see really no difference in doing that and messing around with old computers.
If I had gotten right off the bat, a A4000 all souped up, I think I wouldn't have half the fun with it. The fact That I am starting with a base A2000 and working up, is the fun part. But hey, thats just me. :-D
