One thing I love the most with the iPad is that it's so easy to be creative. There's so many apps when it comes to art, music and photo. Even tho I prefer to create stuff with my own hands and real materials, the iPad is a very nice substitute and it's very handy when you're not at home or traveling.
Of course it's not exactly the same thing to draw digital than "analog" it's a little bit harder, or easier depends on want you what to create. Anyway here's few of my latest drawings that I made on my iPad:
