Here are two Multi platform apps you should review

[cocopuffz]

Gmote is available for both the iPhone and Android. Control your pc/mac and launch apps/movies and stream media back and forth between devices.

OnAir is a over-wifi file transfer tool. It's not only available for iPhone, Android & Windows Mobile but it's also multi-platform. It connects to Linux, Windows & Mac.

I really hope this show doesn't end up just an iPhone app show. There are some great apps showing up on Android and Blackberry.
