The 9600 is quite a different product. You have to rework all the graphics. If the reliability claims of the database IR codes are true, you will probably want to use them too. THe 9600 and 6400 screen size is different. The hard buttons are different. I don't see much benefit in trying to convert an existing icf file. The ProntoNG owners are finding little benefit to conversion even though the 9600 editor will convert an NG ccf or pcf file.

BTW, I've already seen the 9600 advertised at $999, $300 off the MSRP, and this is only the first week the product has been released. I think we will see lower prices in the near future.
