What's the most important item in your bag?

Chambers: Easily my Blackberry. Recently I had one melt down, and I felt frantic for a few days. I just can't deal with the keyboard on the iPhone. I'm a super fast thumb-typer, which comes in handy for quick cab rides between meetings.

I tote my iPad around for impromptu meetings with investors. I love taking them through photos of our stores on the glossy screen. In downtime or on airplanes, I love dreaming about my next cooking adventure with the p, and catching up on blogs with . I also recently downloaded a Backgammon game app. I'm secretly practicing to beat my boyfriend in our next match.

Do you carry a laptop?

Chambers: I switched from a PC to a Mac when I became an entrepreneur, and Apple is increasingly taking over my purse. My new is amazingly light and thin. I sync it up to an external hard drive and monitor when I'm at my desk.
