Dynavox Acquires ERICA

In yet another acquisition announcement Dynavox now owns Eye Response Technologies makers of the ERICA system.  (Previous mergers and acquisitions include Blink Twice (the Tango) this past July, Enkidu in January 2004,  Mayer-Johnson and Dynavox merged in May 2004 as Dynavox left Sunrise Medical).  Dynavox also today filed a registration statement with the Securities and Exchange Commission for a proposed initial public offering of its Class A common stock.  (Coincidence?)

This merger could be good for customers, the ERICA had one of the best eye tracking systems out there, but the software is so-so.  Dynavox is well known for its comprehensive communication software.  Currently, however, the Dynavox EyeMax uses an eyetracking system developed by EyeTech.  This leads to all sorts of questions around how and when (assuming it happens, they could just be eliminating competition) the EyeMax will move from being EyeTech based to Eye Response Technologies based. 

My larger concern is with the Mayer-Johnson/Dynavox empire as a whole.  They are getting bigger and bigger each year, but are they true to their mission?  What are your experiences?
