This I don't really get. In fact, this was one of my problems with the film: it treated what should have been a gigantic, vast area of space and effectively reduced it to the size of a solar system. You get from Kronos to Earth in the blink of an eye! You can see Kronos from the Neutral Zone! And not with your long-range sensors - with your eyes! It was like the filmmakers didn't get how big space is.
I think in it's world building, it's attention to detail, and with showing us a real away mission as well as conflict spanning the stars and the Klingons, the movie is unparalleled within Star Trek. JJ Abrams creates more believable worlds in a few scenes with almost no narrative than even the TVs shows often did, much less the movies.
In order to have scale you have to cross scale...hence the faster speeds, and transwarp beaming. I don't have a problem with a greater star-spanning ability, look how well Star Wars did it (even though Lucas apparently didnt understand what a lightyear or parsec was).
