I just got a Playbook. I chose it over an iPad because I like a challenge.
Today's challenge is trying to purchase a book on kobo. First the purchase function would not work on my Playbook: no matter how many times I carefully entered my credit card information the purchase would not go through. Then I purchased the book through my Mac. Logged onto the kobo app on my Playbook and there is the book - only it will not open. Message: "Sorry! We couldn't open this item. We're working to fix the problem - please try again later." Kindle web works however. I may go back to Kindle.
