I wasn't going to buy the iPad. I have an iPhone and a 17" Macbook Pro. However, all your positive reviews have changed my mind. Will be picking it up Monday at the Apple store. So, here's something we can all help each other with. What are the most essential iPad apps that will make this device more useful than it already is. And, what are your favorite apps (games and productivity)? If possible, list whether the App is FREE and if not, the cost of purchase.
