I agree here with HappyDaze, we can't analyze the StarWars Universe compared to ours because one: it's Space Fantasy, and two: it's not our universe. In addition, all ships had targeting aids, but yes, everything was by hand targeting, outside of some examples of turret control. I also don't believe that just because StarWars was shot in analog, that everything was low-tech. Star Trek was shot at roughly the same time and the whole feel of that is much different in comparison.
The fact of the matter is, George Lucas wanted a low-tech, high-tech feel for 'his' Universe and really, the only way to explain nit is using 'StarWars' science, not our own. Just because wireless devices exist in our 'real life' doesn't mean they need to exist in StarWars; perhaps people are okay with commlinks and the holonet, they don't need wireless internet, because they've got droids, hyperspace travel and machines to basically do everything for them. And if slicing is so easy, perhaps having such devices is just walking around asking to be hacked... If everything was wireless, slicers would have a field day! Or perhaps no one every thought of creating it.
Maybe targeting systems of vessels in StarWars with Analog targeting measures were best suited for space combat... We can't think of facts stating that they don't work with our combat fighters and say that they won't work in StarWars.. And, if anything, I believe things like Proton Torpedos and missiles have 'lock-on' and blasters/lasers (miniguns or cannons) are manual targeted (like they still are in our universe).
I just think, trying to compare what 'we can do' to what 'people can do in StarWars' isn't exactly a fair comparison - we don't deal with the same circumstances which the average person in StarWars has to deal with on an every day basis. The world was made to work for them, while in real life, we make things to help us out with our circumstances.
