Hi there.
This is my first post here. I was a huge Amiga fan back in the 80's-early 90's, owning first an Amiga 500 then an Amiga 1200. And while I don't have either system any longer, I still have fond memories of those days. I've yet to find a computer that gives me the same feeling my old Amigas did, although my 20" iMac comes close.
I've thought about picking up an old Amiga again just to tinker with, but the more I think about it the more I think AROS with UAE integration is the way to go. That way you can run it on pretty much any Intel box (provided drivers are available). Plus, there are a ton of open source projects like Mozilla and Openoffice that could be ported over. An AROS system running Firefox and Openoffice, as well as all of the old programs and games would be a pretty nice system.
Hopefully AROS continues to improve and open source programs like Firefox are ported over. I have a spare PC that would make a great AROS box. :-)
