Blackberry Playbook

So this last March, while journeying to the Game Developer's Conference in San Francisco, I was able to score me a free Blackberry Playbook tablet at their booth. Now, forgive me, but I'm completely unfamiliar with Blackberry and all things RIM. My phone is Android, and before that I've never owned a smartphone. I've never owned a tablet at all (my parents own Kindles). In short, I'm rather clueless when it comes to what a good Blackberry can do.

I really like the tablet itself. It works great, and it looks great. I thought maybe the OS would take some getting used to, but it's clear, easy to manipulate and, above all, intuitive.

The only real downfall I've experience is the app market. There just isn't much there. I can understand why they were trying to push the tablet so hard at the conference - they desperately need app developers on their side.

My question is this: What quality apps are really out there for the Playbook? I have some good games (such as Plunk! and Doodleblast), but every time I look I just come across the same crap over and over again. I also have Kobo, which isn't bad, but wasn't there going to be a Kindle app once upon a time? What happened to that?

Any suggestions are welcome :) I want to get the most out of this tablet, and figured this was the best place to ask.
