I don't need stats or numbers, because I don't have a reference point to judge those numbers, like I do with a computer. Instead, I need insights like this, things that actually help me figure out how it will fit into my life:
I stay up until 4am the night before the first day it's on sale, searching for iPad specific apps. I find very few high-quality programs, but I do find some: Words With Friends, an asynchronous scrabble clone. Wundermaps, for keeping an eye on snowstorms using radar animations. Netflix streaming, Pandora and the Epicurious cook book. And after I find these few, I start loving the iPad more.
