The trouble with Star Trek is the bizarre time-jumping that they thought was cool ...
It got over the top in Voyager, and just got worse with Enterprise (which I found nearly unwatchable, especially when you can point to Andromeda and pick the bits Enterprise stole ... yes, yes I know they are both Roddenberry).
Unfortunately, it made an appearance in the new ST as well ...
Bottom line, whichever Timeline you use, someone will complain its not canon, except for the original series (which, annoyingly, also had a few time travel events in).
It's not a big whinge, I AM a huge ST fan, and the new movie was surprisingly good ... its just the time travel seems a far too easy 'storyline problem resolver' ... similar to Bobby Ewings Dream Shower Scene for an entire season (I think).
That was quite a meandering post ... sorry
