Peter Mansbridge of The National (the flagship nightly news and current affairs program from Canada's public broadcaster, CBC) uses a BlackBerry PlayBook during the show. He has it propped up in what looks like the convertible case, and it looks like he has his email open, maybe in preparation for breaking news or story updates?
I love my BlackBerry PlayBook, and find more ways to use it everyday to make life more convenient, and more enjoyable. It's awesome to see other people doing the same. I know some of you must be doing some fun stuff with your PlayBooks, or using them in some unique way no one else has thought of, so go ahead and share in the comments ways you use your PlayBook that others may not.
