And the Tasman engine that IE for Mac was built around was much nicer than the Trident engine that powered IE for Windows. IE for Mac had good support for CSS and support for transparent PNGs many years before IE for Windows did. I always wondered why MS decided to fix up Trident to create the original Edge instead of porting Tasman to Windows.
I have a memory of browsing on my mac with 5 staggered internet explorer windows (this was before tabs, and I was clearly showing my tab-addiction to come already then by using five windows in parallel.)
