I use my MorphOS machines daily for most of the stuff I do: browsing the net, doing mails, programming, reading pdfs, videos, pictures, music, editing html, playing a game from time to time, spreadsheeds, etc.
I use Windows/Android for wordprocessing, a few google services, tax services, skype and some development stuff.
MorphOS is doing a pretty satisfying job here, but having an additional random Win box and a tablet makes life even easier. The good thing, due to having MorphOS as the everyday machine, the Win box keeps very clean and hence, stable and fast.
