Because of this.
These, along with millions of other flip book animations that have made a parnership between Nintendo and Hatena a success in Japan in such little time.
What am I talking about? The Moving Memo Pad, one of the first of soon to come DSWare apps, and this one has really gotten alot of praise.
The story behind this was that Nintendo made a partnership with a japanese website known as Hatena (have no actual idea what they are), where a special upload service is set up for DSi owners to share their Moving Memo Pad creations.
And look at how successful it was! http://ugomemo.hatena.ne.jp/
Some of them are duplicates, yes, but you have to be impressed with stuff people came up with.
Not only do I want a DSi now just to try out my art skills on this thing (and try doing an actual animation in my life), but also there may be a possibility that Nintendo will do the same for other regions, making partnerships with outside sources or groups to provide content. It's working well in Japan, and it could happen in the states, or everywhere else.
I'm almost getting impatient for this thing to get released worldwide. I personally don't care so much nowadays for the GBA slot, since I don't play GBA games anymore, and this app along with others in the future seems to warrant enough an instant purchase for me.
