So in shopping for apps for our WP7's today, I came across a knock-off version of Osmos called "Cell". (
http://wpcentral.com/cell-review) Very similar in many ways, but nothing near as polished as Osmos in all its variants. It made me sad, once again, to realize that Osmos isn't available on WP7 yet. I, for one, am begging to buy the real thing!
... and not available in the Xbox 360 Indie games marketplace either, where it could make a killing. As of the beginning of last year (pre-Kinect), there were 30 million Xbox Live subscribers (who can easily find & purchase Indie games). By now, it may be close to as many as there are iPhones in the wild. (50 million) It's all the same dev plaform: XNA!
