I used my A1200 every day until late 2004 when OS4 on the AmigaONE started to become usable for an everyday system. I never had a Windows PC until about 2006 when I was required to use one for a college course.
Now I use mixture Of OS4.1 and Windows, mainly because OS4 has no convenient way to watch Youtube and I also sometimes like to watch programmes on BBC iPlayer.
If youtube worked in OS4 web browsers I could probably ditch windows altogether, any creative work I do is always carried out on Amiga OS.
I do still have a CD32 and also have Minimig but they don't get used very often. I think maybe 5-6 years for the CD32 and perhaps late last year for the Minimig.
