They showed it at CES in 2010.
Now finally it seems that the device is about to be released.
To me this device has the potential to become the ultimate device because it uses very reliable magnetic hardware for the tracking. But the most important is that they include two handheld controllers that include buttons but mostly I really like the price!!
We actually went to reputable companies in the tracking industry back in 2003 and wanted them to build exactly this device. Unfortunately we fell about 200k short to have them engineer this on our behalf 🙂
