I own a BB Playbook. I'm a big fan of the beta OS 2, which BB is set to release the official version in Feb. For $200, it's tough to beat.
What I love: it's the same size as the original Kindle, so I can fit it in my coat pocket, cargo pocket (if wearing shorts), and depending on the pants my back pocket. It has the best specs out of any tablet you can get at $200. If you have a BB phone, you can tether it to get media away from wifi without having to purchase an additional plan.
The biggest gripe anyone had for it was the limited apps, but that's not really a problem if you upgrade to the beta OS 2 because you can sideload most Android apps. (I'm willing to walk you through this if need be, just PM me.) Once the full OS 2 hits, it shouldn't be a problem at all. The next most common gripe is that it's too small. This is an odd gripe because few complain about the Kindle Fire being too small, and it's the same size. Plus, with the drop to $200, more consumers bought the BB Playbook. The mindset behind the price drop was to penetrate the market to help spur app development specifically tailored to the BB Playbook.
The other tablets I considered were the iPad and Galaxy 10.1. Both seemed to be handled more like netbooks and cost almost as much as one, yet lacked the same amount of power. Neither seemed to be more than twice as good as the PB, and I didn't need a ton of apps.
I use my Playbook mostly for keeping all of my work notes in one place, a media device for when I'm traveling (mostly for work and the flight movies don't update often enough).
