Thinkpad Tablet 2 (& Others) Wacom evidence! (TPT2 $629)

I've been looking all over to find out whether the Thinkpad Tablet 2's digitizer was Wacom, and I think I found my (very trustworthy) evidence:



It comes from this page:

SOFTPRO - Signature Capturing Technology

Which is a signature recognition company. They would seem to have the best knowledge outside of Wacom as to who uses which technology.

We knew about the Vivo Tab, but this also confirms the Ativ and Thinkpad 2 to have Wacom!
