Hey having old Amigas is like old cars, it's an hobby of class;) But I agree that it can start getting too much of one's time so watch out for that cause it might not be so good, I myself been considering selling my A4000T for ages and just keep the 4000D and an desktop A1200, but I keep finding excuses!
One of the special things about this community is that you're contributing to an OS that's special, that you like, and that might at some point be accepted in some niche markets.
But for that we don't need to have a collection of classic Amigas, just one is enough, so I think I'll eventually sell the A4000T, for now I just keep upgrading it!!!
BTW, if you want to keep the hobby I suggest you learn programing on the Amiga, it will give you a different perspective of things, but very important, don't prioritize it over other more important things in your life!
