Landing page feedback for Commuter Pal AKA I May Be Late

I'm testing out a landing page (http://www.imaybelate.com) for my iPhone app's relaunch. If you're a London commuter please take a look. If you're not interested in signing up, I'd like to hear why. I'm trying to learn from this exercise to see if I can improve on the landing page to really test if anyone is interested in the app.
