And that's fine for you and me, but limits its adoption (hence appeal, hence longevity) to people that download unofficial, unsupported third party clients and manually set up cron jobs.

The reason Dropbox is kicking ass is that nobody wants to deal with the manual work. Download a program, put stuff in folder, stuff appears elsewhere. No thought required. Simple.

I had to stop using Dropbox because it was unusable on Linux. It leaked memory, hogged CPU cycles, and cranked up IO Wait times.

It was simple and thoughtless, for sure; and that reflected in its decrepit behaviour.

I've been using Dropbox on Linux for many years, and it's definitely had some occasional issues with memory leaks, and its general CPU and memory usage has definitely increased. Used to be it never went over 100 MB RSS, but now it's always well over that, at about 250 right now.

Anyway, I run it at nice 5 and "ionice -c3", and even though I'd like to switch to something else, I still haven't found anything better for Linux use. Everything I've looked at has some issue that makes it a non-starter.

;)

Oops, I meant ionice -c3, not 18. I run a backup client at nice 18.
