Long, long ago, I owned a computer that was so reliable that it only ever crashed on me and caused me to lose work once. I remember it well, and I was livid about it. So much so that I never used that word processor again. And the computer never crashed on me or caused me to lose work again.
That computer was a Commodore 128.It was slow, it didn’t multitask, and I could barely type on its awful keyboard, and it irritated me that MicroLeague Baseball took 15 minutes to load if I wanted to use its General Manager and its Stat Compiler add-ons (of course I did), but from a pure reliability standpoint, that simple machine was the best computer I’ve ever owned.
