I think it killed the performance on a lot of the systems in the Labs for years because everyone had their own copy of it, but it wasn't being shared, and so they wasted huge amounts of memory back when memory was expensive. ↗
By the time I got to record my first album, I was 26, I didn't need pen or paper - my memory had been trained just to listen to a song, think of the words, and lay them to tape. ↗
I currently use Ubuntu Linux, on a standalone laptop - it has no Internet connection. I occasionally carry flash memory drives between this machine and the Macs that I use for network surfing and graphics; but I trust my family jewels only to Linux. ↗
