This would make the most sense. That way, anyone, anywhere on the ship would be able to see whatever there was to see "out there." Of course in deep space, more often than not, there is no "there" there. Being able to see "out" is as much a psychological need as it is a practical one, even if one is seeing a black void most of the time.
I always thought it would be neat if crew quarters on a starship had a view screen on a wall that was like a window, and any scene at all could be replicated as if it were a live 24-hour view, even with weather changes. For example, if you wanted to imagine your quarters were on the penthouse level of a skyscraper in Manhattan overlooking Central Park, that would be your view, day, night, sunshine, clouds, rain, and snow (or whatever you may want). Relatively speaking, the technology for such simulations would have to be fairly easy to do in the 23rd century.
Considering the fact that starships would naturally travel at various angles that would seem "unnatural" to beings accustomed to terrestrial movement (the ground is "down" the sky is "up) I imagine that viewscreens would have to be carefully controlled so as not to induce vertigo or other motion sickness based symptoms.
