im concerned with the Title:
Continue what you started or move on?

thats worrisome to say the least. you mention here that Dophin 8 is not new, that it is all of what 7.1 was supposed to become. then you further state in your announcement that you have scapped Dolphin 7.1, you have scrapped Trident.

my answer short and sweet is that you are not dealing with a house here. you are talking about an evolving system, thus this requires updates and upgrades, as well as new releases. but you cannot see more confuse the two.

you have to Finish what you started. if you are going to put in a new window, so you get the sawzall and the scaffolding, you cut the hole size you are wanting.

and you stop

yeah hole in the wall, scaffolding as your scenic view, and you stop

so that is the answer, do you finish what you start? or move on, and decide to build a deck on the back of the house?
