This is going to keep me from getting smushed by a car, you wait and see.

Totally downloaded the Email 'n Walk app for my iPhone this morning.

I even paid $0.99 for it, because I need this.

You can shut up.

Email 'n Walk (free for a limited time) is frankly kind of a silly iPhone application, but I couldn't resist talking about it here. The idea is simple: start up Email 'n Walk, type in your subject, and start typing a message. While you write, Email 'n Walk uses your iPhone camera to show you what's in front of you so you don't run into anyone. I took it for a test run outside our offices here in San Francisco and even though it felt a little silly, the app works as advertised. When you're done, hit send and you'll be transferred to the iPhone mail app to add recipients and send your e-mail.
