I suppose it's fitting that I should be the one to write our PlayBook review. Before Android and the iPhone, there were two mobile platforms/devices that I was hugely fond of: the Palm V and my BlackBerry. In fact, it wasn't until the iPhone that I finally let go of my last BlackBerry - moving on from the email era into the smartphone age.
Today's BlackBerry is of course very different than the devices I used in college. And the PlayBook is unlike anything RIM has ever done.
I don't believe any tablet maker has perfected the formula just yet. I made that abundantly clear in our review of the iPad 2. While you can't argue that Apple is the forerunner in the smartphone based tablet space, over the long term I still believe this is anyone's game. Remember, the leaders in the early days of the PC industry weren't the ones who ultimately dominated the mature market.
