Probably 95% of my time in-game has been solo. I enjoy playing with my son, whose computer is just in the next room, close enough to talk to one another at normal conversation levels. We always play in a private instance though, never open. And all we do together are combat missions, as that's what he enjoys. He'll mine platinum and grind for mats to engineer his ships, but he doesn't do exploration or hauling. He's never been any further from the bubble than the nearest group of Guardian ruins.
In general, I am not a good PvP'er in any game, including Elite. In other MMO's in the past such as LotRO, Rift, etc, I always just play PvE. I know younger players are way better at controls (i get panicky in PvP and become a button-masher) and have more free time to grind better gear, so I just get slaughtered. I'm too old and have too little time to tolerate griefers as "just part of the game"!
