1. Dropbox automatically syncs all files right away. Github requires manual push, and does not sync new/unstaged changes (like intentionally .ignored .env files).

2. Private repositories used to be a Github paid feature.

3. Less "clutter" in my Github account.

4. More generally, I keep almost all important non-OS files in Dropbox including my home directory and portable apps.

- Simple way to ensure the files I don't want to lose are backed up.

- After a fresh OS (re-)install, just installing Dropbox gets my system 90% set up and ready for use.

- (Theoretically) I can work on my files from a USB drive on any computer.
