actually in reply to earlier comments not every civilization and race in star wars is at the same tech level. Look at the Ewoks. and if you read the star wars books you see that while the Wookies do have access to the higher tech levels they till don't use most of it. I am surer there are other examples as there are examples of civilizations with totally higher tech. And unlike Trek civilizations from other portions of space have a different tech (visa-vi the Vong and there organic tech in the New Jedi Order Series of books).

And i don't remember for sure but i think they did do something with cloaking devices in the Zahn series.
