I upgraded from 4 to 5.5 at a cost of $180.00 about a month before they announced that they were coming out with 6 for an additional $180.00. I was so mad that they didn't offer any kind of break to people who had just bought it that I didn't buy 6 until about a month ago because I needed the type capabilities for some stuff I was doing. Now here comes 7 a month later. I can't win. Mike
