Two things about this stylus . . .
1. I found the journeyed one here: http://www.journeyed.com/item/Wacom/...Pens/100908702
2. The description says, "Important; If this pen is not designated as an exact replacement for your original pen, please do not attempt to insert it into the pen holder of your Tablet PC." -- and its picture is the same as Amazon's.

Both pictures show a switch, so I believe them: it's not to be shoved in the PE's pen slot.

Oh, well.
