Great post by the company that created the iPhone and iPad game Osmos [iphone|iPad] on Game Smoothness.
After a few months of work, we were starting to be satisfied with the game's performance on the iPhone, when Apple announced the iPad. We knew this large touch-screen computer would be the perfect device for Osmos. Being lowly Canadians, we couldn't get our hands on an actual iPad till many months after the U.S. release.
Great game, I bought the iPhone version, can't wait to see it on the Retina display when I finally get my iPhone 4. I do recommend it, it's a fun and beautiful little game, and hey, gotta support my fellow Canadians!
