It'd be interesting if there was some sort of system, like instances in WoW, where you're joined by your companion only in certain areas or missions where you're the only player there. That would go a long way toward making your companion feel more special and unique, instead of walking past 5 other Smugglers, with their own Bowdaars in tow, on your way someplace.
I agree that it is kind of lame, like a second-rate Han and Chewie. His backstory is kind of interesting, but he could have been something a lot more cool.
My working theory is that your companions will only join you in Story Missions. And nothing else. When you decide to continue the story, you'll end up selecting which companions you will need. The powerful warrior? The sly smuggler? The handy astromech droid? And then continue on with your mission(s). Perhaps changing members if you need to. I'm curious if Bioware will let player characters take the place of a companion or just tag along to help.
Outside of the story, I think you'll travel alone and have the option to join with other players for grinding, exploring, and maybe some form of Instances.
This is all conjecture based on what I've read on the official page. I could be wrong, but I'm confident it will play close to this. After all why make a MMORPG if you can't play with (and fight) other players?

I'm still waiting for them to tell me what the companion for the Sith Warrior will be:
I'm hoping for either that blind girl from KOTOR 2, or HK-47.
Or a Hutt!
The Sith Warrior companion is a Twi'lek named Vette

HK-47 will be in it though. He apparently guards Darth Revan's tomb. Looks like a story or perhaps an Instance will take you there.
