I'm not a hater or a troll. I preordered the Playbook and have played with it. I honestly don't know what to do with it. Everything I do on it, I can do on the tablet.
The only thing I can think of is I can watch videos on the bus and surf the net as well - if I don't get robbed xD.
So far i use it to read books on kobo, listen to mp3s,.store all my valuable pics and vids, surf the net, and keep an eye on the stock market via flash enabled nasdaq website. I am able to bring it to work with me every work day and whenever i am out and about.
