I remember at one point the front-end guys I knew were laughing that it didn't even support iframes. But I imagine it eventually got decent enough.

Generally, Safari was kind of middling in function and design until around 2018, when it got more streamlined or something; at least, its apparent performance improved over the other browsers on macOS. It was novel on Windows but pretty limited and just, meh.

Edit: I forgot, the clean, minimalist, ad free reader view on the windows version was very nice to have. Long time ago!

It was fun! It worked well when compared with IE back in the day which isn't saying much, but it was a sensible bedfellow with iTunes and all the Apple mobile support software that was common to run alongside for your iPod. I enjoyed using it as my main browser because it was aesthetically pleasing.

Normal. I used Opera. QuickTime player for Windows was nice. Used it under W2K for most of media things in the interwebs.
