Looking to keep track of your stock portfolio on the BlackBerry PlayBook? If so, you'll want to check out QFolio. The app is now available in BlackBerry App World for free and it has got to be one of the best looking apps for the PlayBook I've seen to date. With it, you can  track unlimited real-time quotes, pre-market and after-hours activity, and you even can make use of a custom heat map to track what's hot right now.
