I worked this way for years in the 80s, when my main platform was the Atari ST. I had a whopping 4MB of RAM and would load the OS from a floppy disk into RAM, after which it would create a decent sized RAM drive that I would periodically save my work to. Compiling and running programs was nearly instantaneous, and everything ran smoothly and silently (the ST didn't even have a fan). At the end of my session, I would save whatever I wanted to keep to disk before shutting down. I never even bothered to buy a hard drive, it was such a pleasant experience. Moving on to other operating systems was an abrupt shock when the time came, leaving me somewhat nostalgic for those days.

I still prefer local storage, though, without a forced dependency on the cloud.
