These dinosaur computers were the last ones that impressed mere mortals, just the box and the Trinitron screen with the SGI logo on it made people think they were in the future.
We know how that ended with Fahrenheit and other problems, but since then, very few computers have had that wow factor.
As for office, we mean MS Word and Excel, which worked brilliantly on Windows, with WordPerfect and the like lagging. For me it was no problem not having Word and Excel on IRIX as we had PCs for those things.
If I remember rightly, it was quicker to access files off the IRIX workstation SCSI disk over NFS than it was to access local files on the PC. Everything was 10x.
