Re: Pen proximity alarm
Ah, good, thanks for the update.
I know of the AAAA format, it's also use in the bluetooth linked Wacom pen for the iPad. Speaking of which, if there is one thing I would enjoy on the Surface it would be the apparent high resolution pen interface - on an iPad, pen nibs are vague approximations because it was originally only meant for fingers, and I thus find drawing on it a pain.
