As a iPhone owner that tries to use all aspects of what makes the iPhone great, has combed neatly through the appstore for any valuable apps. In the process, it's cost me a lot of money. One thing that is really making me worry about the iPad is that I'm going to have to do this all over again. I have 700$ to blow for a pad, but I don't have tons of money to spend on the same apps all over again. I realize that not all developers will charge twice, while some others will. I also realize that due to the larger size of the iPad, iPad apps will tend to be more expensive. Overall, I'm just trying to get a feel of how much people have already spent on apps that they feel essential.
