2nd as this technology becomes more advanced the prices will drop and fast. The first computers were millions of dollars and today a computer that does what those did is about $50, video cameras were big bucks not 10 years ago and today a casio FC100 is under $200. I can see a trackman style computer in the $5000 range in a 4-6 years as technology makes it easier to create and sell.
JMHO.
