I think it is funny how we forget the past. I'm sure we could dig up old rants about upgrading PP software each year. ZO lets you do it for free (Ok, you need the com connection, but I'm sure you can find someone with one). I remember upgrading to a 5" display vs. the square mount for PP and don't forget the single line screen vs. multi line screen. Then their was a fee for going to Star Gazer. These business have to advance and develop new systems. The old pucks were failing, you had to buy new ones. Now ZO has a new single puck, if it has more reliability and last longer, isn't that better in the long run?
I may be forgetting some upgrades, but ZO has been out for 10 years and this new "S" is the third major revision? We had "Q" and "R".
