Er yes, Windows PCs also have viruses and a bunch of bloatware as well. Do you want to spend a bunch of time managing your devices or actually using them?

The other issue is that SQLite uses a single lock on the database, so if you have more than a small number of concurrent updates, it won't be pretty. Still, if there's interest in replicating to/from we would be up for it or would hope that somebody might see their way to add a plug-in for it. In the meantime, it looks like a really handy embedded database.
