One of the things you realize over time as a software developer is that once you build a feature into a piece of software you can rarely ever take it out. The more people that use your software the more true this becomes.
If you watch the following video you’ll notice that photoshop is providing a subset of features on the iPad and since this is a “new” piece of software nobody can complain about all of the features the left out. You can find the same thing with some of the Apps that apple has released including the latest addition “GarageBand”. Maybe this is what truthfully sets the iPad apart from the Windows Tablet PC’s of the early 2000′s. A fresh start.
