Here are my notes (taken on Corkulous.)
The app I rely on most at work is still Note Taker HD. I also use Evernote on an almost daily basis. Of course, you need enough juice to do all this work on the move. I like my new Belkin surge protector. It spins around so you can charge multiple devices no matter what angle you find an outlet. And, when there isn't an outlet around, I rely on my iGo Green for a quick power boost.
