This is so true. I was given an iPad 2 earlier this year and I love it. Reading, surfing, planning, wireframing, does it all.

But doodling? Brainstorming? There is no app in the world (yet?) that can match a pad of paper and a good, comfortable pen.

I use a Wacom pen especially built for the iPad screen and an app called Penultime. Works pretty well.
