Welcome to A.org, it's a great place to visit and I practically live here (or visit almost everyday).
I have found that most people use computers for e-mail, Internet browsing and little else. Of course that is not the case for most people here at A.org, they are computer fanatics and experts in many areas. PC's and Mac's are better and easier for most things, but I enjoy using Amigas and like you, have gotten back into using mine recently. I have found that I am losing many idle hours getting reaquainted with those great old Amiga games.
The other primary use for Amigas remains in the production of videos and still some small brodcast studios. I still use my A4000 for this.
