I can't really think of 5 reasons, but I still use my Amigas for music production...All my early work is on Amiga formatted drives and needs Amiga software to view... And I stay with AROS because it's fun and that's where my history is, I grew up with Amiga OS, it was my main system for 10 years. It's nice to remember why I got into computers, and it's nice to see how far they've come!
