As much as I loved my O2 (my first professional computer), it was underpowered for the time for anything other than texture manipulation. The closed source nature of that time period and the hardware sales motion meant that you were paying through the teeth for compilers on top of already very expensive hardware. The Cray-linked Origin 200's ran Netscape web server with ease but that's a lot of hardware in a time period when everything went out of date very quickly-donated ours! Irix still looks better than the new Mac OS UIs IMO but no-Motif is a small price to pay for far cheaper access to SDKs IMO. Also, Irix was hilariously insecure due in part to its closed source nature. https://insecure.org/sploits_irix.html
