From them internets after the x86 version got out, I think. Played enough with what I found around, and I ultimately bought (with real money) the BeOS 5.0 Personal Edition, made it dual-boot my Linux machine and knew that this is it! It felt like an Amiga but on soulless PC hardware instead! The exhilaration was unlimited! It booted fast, no old cruft, unorthodox designs, everything one-in-a-thousand a true harbinger customer loves!

Eventually I think the setup gradually bit rot with no updates and unsupported hardware, so I reluctantly had to go back to Linux. I remember Ubuntu and Gnome 2 started to look pretty nice (well, for an inferior desktop environment) in the early years of 2000.

(Unsurprisingly, years later Gnome came out with Gnome 3 and killed all the good stuff that Gnome 2 had accumulated. I can only wait and see how long Mate desktop survives.)

I still keep a Haiku VM around and boot it every now and then.
