Accompanying the just-released iOS version of Ms. Splosion Man, the lighthearted platformer is also now available for Steam (Windows only), Games for Windows, and Windows Phone 7. The pricing on those first two ports is $9.99, while the WP7 game takes the same approach as iPhone with its $2.99 asking price.
Based on Chris' review of Ms. Splosion Man iOS and my prior experience with the original Xbox Live Arcade release, I'd recommend going with the title on Windows proper for the cooperative campaign. The folks at Twisted Pixel know how to put together a solid co-op showing to the point where I enjoy those levels more than anything else in the series.
