In one of the AmiWest 2009 news articles here Inertial Computing is mentioned as one of the exibitors on the show. But nothing more about them is written in the article. The article did, however provide a link to their website: http://www.inertial.biz/
When visiting that site I get a threat warning from Sophos:
'Virus/Spyware' Mal/Badsrc-M has been detected and listed in Quarantine Manager.
