Honestly, there is one sentiment here that I can get behind, and that is a hope for more content in the future.
Not in the sense of jobs paying more money or anything like that. Just more variety of missions. So even if you realize you will be stuck with your Cobra for months on end of casual play you won't mind because at least there are different things to do and try.
And of course I believe that's coming, but I can see why some people would want to see it sooner.
Over at Oolite (an open source project building off the original Elite), the guys have come up with a number of ways to keep these interesting. For example, the Rescue, Recovery and Salvage (RRS) Group is an add on that adds a special station with special missions, all centered around pilot and black box recovery and the like. As you go gain their trust you're given more difficult missions.
That's just one example, but it's a good one. More things like that would keep casual players interested even if they felt stuck with a Cobra. At least I think so.
(actually a cute idea to build off the RRS would be that any black box recovery mission is actually tied to a real pilot who died in the game within the last X hours. You have to recover CMDR ____'s black box, and if you succeed, maybe that commander gets some money back from the insurance company (like a tax refund

).
