What's the difference?

What's the difference between the TrackIR and the
SmartNAV? They both do mouse elimination ("ME").
They both play games. With the exception of the
external-switch input, are the "heads" the same?
Does the SmartNAV get the benefit of the "Pro"
technology?

What about software? The TrackIR can do ME, does
it come with the NaturalPoint Application? Will
the game add-ons work on the SmartNAV?

I think what I'm really asking is why are there
two products? They appear the be exactly the
same. Is this a case of two different marketing
campaigns, for two different user communities,
for one product?

Psst, the truth is out there, pal!
Just take a quick walk through the (Smartnav-) forums and you'll find all the answers you need...
