I'm mostly happy with Skill list as it is at the moment, if anything it could be a bit shorter. Personally I find ideas like "let's have separate repair skills for things" hilarious especially in games like Star Wars. The system in EotE is supposed to be a narrative system and more importantly it's supposed to be robust but also easy and fast to run and play (that's how I see it, anyway). If I wanted all those skills I would play SW using BRP. I never did (and I like BRP), instead I used things like FATE, Over the Edge or (most frequently) Savage Worlds. That's because Luke can fly anything, Anakin could fix anything, Han will only have language problems when the plot demands it and Obi-Wan was a Jedi General bacause he was a leader, not a graduate of Republic Officer Academy of Strategy and Tactics (ROAST, couldn't help myself). I don't even mind the overlap, I always allow players some freedom in what skill they choose to use. If two of my EotE players wanted to achieve similar results using Charm and Negotiate or Streewise and Underworld, then by all means go for it as long as you explain/roleplay how you do that. The only danger is a skill becoming an uber-skill, but looking at this game's list I don't see that happening.
Just my two cents.
