As of this posting, 99.
About 8 are paid (LAN utilities mainly, plus that damn BIRD game I'm addicted to 🙂.) Oh, and a paid web browser (alternative to Safari.)
The rest are freebies which get various amounts of use (and many lie dormant which I should delete when I get around to it.)
I find that many of the "freebies" were obtained via price drops to "Free" (using app finder applications) -- so that's where I end up collecting oodles of apps. Interesting in that I keep my desktop/laptop very lean and mean -- no unnecessary crap loaded. But w/this mobile device, I've taken a different road... for the time being.
