There have been large discussions about the brand of the TPT2 digitizer. Most people say that is Wacom, even some third party companies (SOFTPRO - Lenovo ThinkPad Tablet 2). But Lenovo does not includes this information in their specifications.

Anyone has some experience with Amtel or comparison between Amtel and Wacom digitizers?
