Most of what I do is creative, a mix of Art, music, programming, writing. I've done things like covid data analysis, I've written the odd letter on there, some of my newsletter gets written on there. I also use it for things like Usenet, IRC, Telegram etc. There's also a lot of really good games for it. I've heard classic 68k Mac owners have similar experiences. Of course, some say the Amiga is also the fastest classic Mac[1].
