Do you use a app on your laptop or desktop to view Facebook? Of course not as the browser can handle the html and so can the playbook. I rarely use apps because the browser on the playbook can access 100% web sites unlike ios and android. Why the app was created was because the devices inability to access a full web page because the lack of os browser ability to render a full page 'iOS and android'. It amazes me how stupid and clueless some people are.
