Of all of my problems with the Prequel Trilogy, the only thing that irks me more than the dialogue is the technology. In the original trilogy the hologram of the DS II is the most advanced non-weapon tech we see, yet in the Prequels we see holograms and hovering stuff everywhere. To make the Prequels seem more like they take place many years before the Originals, the Naboo ships will no longer be extremely polished and the display screens will show dots and lines! Instead of making OT tech comply to the prequels, prequel tech will comply to the OT!
In a totalitarian dictatorship such as the Galactic Empire, it is only logical that all non-military technology would decline.
A small band of rebels fighting an evil Empire could hardly be expected to have state of the art military equipment!
