Well Sander- I have to admit I sympathize. I think part of the problem you might be facing is that your character is a bit limited. Basically Pipboy is anything but a combat character, and while this is role play, its role play that is combat heavy.
One thing might be to give your character a bit of depth and darkness. We don't know this fellow, but he is a survivor and he's been on his own for awhile. Chances are he's likely not to reveal too much and I am guessing, if you play him darkly, he might be a bit of an opportunist and a sneak. He could also be a lot smarter than the rest of us think.
But also, don't be afraid to play other characters or creatures. There is nothing wrong for writing from the vantage of a Trog in the current encounter, or even getting a bit into one of the NPC's minds. We have some pretty well drafted NPCs already. We also still have some weakly constructed player characters. We can't be sure how often some folks will play or how they will develop, but there is no reason you should feel reluctant to take the initiative and develop it.
For example- in chapter 2 my character was pretty much out of it for 50% of the chapter because of wounds. Still I had some opportunity to post. My favorite bit so far in this has been the story of the techs in the Delmar Depot (and they're dead!).
As gunslinger posted, this is amateur writing really. Its not really role play but more cooperative novel writing. Feel free to take the story as you will. There is a central plot, and there is structural direction, but there is lots of room for variation and creativity. Mostly have fun with it.
Don't feel constricted by your character.
I like mine, Grimm, but then we got Talon, Reed, Hook, Nat, McReady, Thing 2 and Thing 1, we got an absent Rudy Kafka, and a currently quiet Gabriel, Rogue, Virgil, Jim, Buffy and Blade. So if you feel constricted with Pipboy, play one of the others. All these characters need a bit of life, and you are more than welcome to inject them with a bit of it when you can.
