If you remember our previous post, we were talking about the different keyboards in HP12c's of late. Seems that it is due to products from different factories - the big % sign coming from the Invertec factory and the small % coming from Kinpo.
Here you see the codes on the back of the unit: IN04 and KN05.
Now, all the new 12cs I am receiving belong to the "big %" type...except the new HP12c Anniversary (due in Europe from next week on!)
(By the way, the HP15c Limited Edition comes as well from the same factory, and you should expect the same quality - I can attest it!)
