A cheap backup pen

[surfdock]

OP's review shows different thread pitch on the caps of the two pens. So if you interchange them you could ruin the threads and the cap might fall off in the future since it wouldn't be secure since they would be cross-threaded:

But you could always hold them together with scotch tape I guess - its not like you need to swap the batteries every day.

Fortunately the Sony stylus threads are an exact match to the SP3 threads. This image shows the Sony top on the SP3 body. I will post photos later of the Sony body with the SP3 top and one comparing the threads.

I think no stylus can compete with the Surface Stylus, love it!

I think they should sell the pen top for $10-20 or something, so that other N-trig devices could utilize the OneNote button

i wonder whether the stylus from the 1st generation thinkpad tablet will work or not

The Lenovo Stylus of the Android Tablet works! But I think you can't buy them anymore.
