Just wanted to say that I bought a playbook a while ago because it was cheap. I own an iPad but even though I have been using Apple since 1980 more and more I find they have become "the man" with walled gardens and closed systems.
Overall I was really impressed with the Playbook and love how easy it is to use as a hard drive. Love many of the features and sideloading stuff.
The major negative is the crappy browser which is slow, has no "back" gesture, the "back" button is hard to use without hitting something else,and wont accept AdBlock (which is kind of a deal breaker for me). The other browsers that are available are crap too--amateur hour. I am really surprised how little anger about the lack of browser choice there is on sites like this. I ask that all Playbook fans email BB and say we want an adult browser. And send out a call to the open source community for somebody to port Firefox in a way that works.
You folks here know more about 10 for the PB than me ...I hope that it will contain a surprise of a better browser.
