If you have an iPhone you can have this now using MyWi which turns your iPhone into a Wireless 3G hotspot. As it will prevent the need for me to have two data plans I actually prefer this to the 3G iPad. It does suck up a lot of iPhone battery power though.
Just watched it again, looks pretty cool:

Well, that demo really answers a lot of questions I had and pretty much has convinced me to wait for the iPad. The HUGE difference between this and the Cintiq is:
The Cintiq is not wireless.
You can not take the Cintiq with you everywhere.
And, unlike the Cintiq, you do not need a pen (stylus) with the iPad.
Looking at the vid, he was able to choose line width and vary the brushes. I like that. I can not imagine what it would be like to paint or draw with a finger.
As for the iPhone - I am going to stick with my Google Nexus One and stay with Android on the phone.
I do have an iPod touch and will continue to use that for entertainment. I will download the Brushes app to the iPod and play around with it.
I have to say, in my opinion, the iPad may be the absolute game changer for the computer world and the industry and the internet. I was reading a study about the sales of netbooks suddenly dropping as people were anticipating the iPad.
And for the creative folks like me? I can not think of a more intuitive product ever. Imagine an artist or director being on the set of a movie or making a film and instantly changing the storyboard or script and then rendering those changes in how things should be. Imagine a director having the ability of using an image or snapshot and, instead of just giving directions or changes, can actually take this pad and demonstrate exactly who or what should be where and how it SHOULD look. This is an instant mock-up tool, instant layout tool, instant editing tool, and all in one convenient lightweight package that can be taken and used anywhere. Seriously, that is how excited I am just looking at that demo.
