I agree and disagree on several of your points. I agree that they have to cater towards the non-trek fan to put bums on seats. I feel the main focus of the problem that I and from what I have read on the boards is they are not showing any regard towards the TOS faithful in regards to the look of the film.
Since alot of the modern day trekkie was introduced to trek through TNG onwards they are so used to LCARS covered bridges they show little regard to the origin of their design. And if they are not careful the 24th century ships will look more primitive than the "re-imagined" 23rd Century ships.
I just feel they could have updated it without a total redesign. Every trek series or film from TMP through to Nemesis has always started at the Matt Jeffrey's design for a starship. It has been proven that you can update the look without making it unrecognisable (case point TMP bridge and Connie refit).
As for the story I will reserve judgement until I have seen it.
"It's going to blow and suck and nobody will go see it because the ship looks a bit different"
I'm sorry but from the pic I posted above it is more than a little different, though not a overly bad looking ship the Enterprise it is not.
just to conclude my rant. I like the casting, have to reserve judgement on the story. But so far I don't like the visual changes to it.
As a side note I was the same about the Transformers live action film until I saw it, and liked it
