this. a thousand times this.
I can type fast than I can write on a tablet. After numerous stylus failures I just gave up and bought a bluetooth keyboard. I tried the clip-on minisuit but it was too small and is missing a tilde which I use all the time while programming. I've settled on a full size $20 Anker keyboard which is the size of an Apple keyboard. It works great. Just get a stand to prop up your N7 and you basically have a tiny computer.
Here you go.
