I recently attended a session at CodeMash 2011 called Mobile Smackdown. During this session Jeff Blankenburg (WP7), Chris Judd (Android), and Dan Steinberg(iPhone) set out to create a twitter application in 15 minutes or less. I thought it was a great session. I found it very interesting to see how the same application was implemented in each platform. In the session Dan was the only one to finish the application within the time limit.
Once I got home, I was curious to see how hard it would be to create this application in 15 minutes. I also thought others may find this interesting, so I created a screen cast of my attempt. I wrote the application once without worrying about time to make sure I had everything down. I then went through it once as fast as I could, but I did not run a timer. The attempt in the screen cast is my 3rd attempt.
Kudos go out to Jeff, Chris, and Dan for an entertaining and informative session.
