The Naboo Starfighter matches the technological stylings of all the other Naboo ships and speeders so I don't have a serious problem with them, though I might take down the colour a little (and have different colours for different squadrons, as I suggested earlier).

If they were in line with the same sort of colours as the astromech droids that would be fine.

But I'm fully behind the idea of slick Y-Wings, X-Wings etc being Republic ships it makes sense that the Rebels in the OT are trying to maintain and enhance old ships rather than building new ones.

It would also make sense to have some of the Rebel ships on the Separatists side too.
