In the 90s, at SGI (at least in France) they had Macs as workstations for tasks that didn't require or weren't compatible with an expensive SGI computer (like running MS Office or sending faxes). They switched to SGI Indy and O2 (running SoftWindows95 to run MS Office) at some point around 95/96, but that was a pretty expensive option, and Softwindows95 was a dog unless you had a really fast R10000 O2.
