In North America I think they're remembered as computers that were MS-DOS compatible, but not PC-compatible, and thus kind of a dead end. Like the DEC Rainbow or the Tandy 2000.
Some were, but Olivetti moved into PC compatibles. I’ve used many PC desktops and servers with their brand (and design!).
I have a complaint however. One family of desktops seemed to demand blood sacrifice every time they were serviced. You’d open the machine, replace the failed drive, test, close it up, and a cut would appear in your hand. I don’t remember cutting my hand on the sharp edges inside, but there was always a cut afterwards.
