It's a gimmick, but I've enjoyed playing with it.
I want a flip case that opens upwards like an old school notebook. Bonus points if it's magnetic and attaches to the mous limitless.
EDIT: This thread is about a Pen... I want a notebook style case to store it in to have a notebook and pen, largely to feel like a film noir detective when I take notes. I've clarified, as the concept of a notebook and pen is apparently more difficult to grasp than I originally thought.
Hmm. That's an interesting idea. I did giggle about the detective thing.
But to be honest with you, as long as I've had notes, I never ever had thought of, say, as you stated, the pen being up top, with a flip, up and down motion, and possibly pulling the pen out from the side. Very, very clever idea IMHO, and in that case, I would like it more than even the way the note pens are stored.
It could also double a a stand, with a possible added benefit of the magnetic system, being "under" the bottom lip of the phone.. That would indeed be very cool(I know you didn't mention that, but your idear got my mind rolling).
Hmm.. Interesting
