Samsung's BlackJack is similar to Research in Motion's BlackBerry but with more multimedia features (at the the time it was launched) with an okay keyboard and 1.3 megapixel camera.
It uses Microsoft Windows and it's a light, thin device that's easy to use (if you like Windows Mobile). It feels good in my hand.
It's not perfect. The keyboard is cramped in some areas. It doesn't get mobile TV.
But the camera is at least as good as average, probably somewhat better than the typical 1.3 megapixel camera phone -- although what's "typical" continues to improve.
The videos aren't available at the highest resolutions (as in 30 frames per second) but they are good for lots of uses. They will serve the needs of many users.
Overall, I like the BlackJack.
