One of my favorite points about SQLite which hasn't been addressed yet in the comment thread is that its databases are just single flat files. Need to copy data from a server to a local dev machine? No need to log into the server, make a dump, copy the dump file to the local machine, and import the dump. Just copy the database file as you would any other file. That's it.

Making a backup before trying something risky (and then restoring the backup when something screws up) is similarly trivial.

Maybe to some of you it's not worth that much, but it's a legitimate timesaver in my opinion.
