Yes, you can use it for creating but it's not its primary purpose. Just as you can use a laptop for reading books. The experience is just so much better on an iPad.
It's a "lean back" consumption device not a "lean forward" production tool.

Actually, this is one interesting spot that netbooks fill in the PC ecosystem as well. I use Kindle for PC all the time on mine, but then can still write blog posts, touchup images, etc. I'm not saying it's better or worse than an iPad, but it is filling a unique need, and I'm amazed how much different a computer feels when you can carry it around so easily (10 in. screen and <1kg) and still use it for a whole day. It's the promise of laptops, portable computing, fulfilled. And yes, it's way more a content consumption device, even though it's a PC. So there :)
