The fact that you've got limited space is a good thing. Getting rid of extraneous stuff is more emotional than practical and if you start playing the "what if" game you'll never give anything away. Start with your EDC and work outward from there. I recently went through something similar with various gadget adapters, cables, battery chargers, etc. Talk about a nightmare. I couldn't even remember what some of them were for. Its 2011, we've mapped the human genome but can't standardize the plugs for computers, cell phones, mp3 players, etc? Good luck dweste, I applaud your streamlining efforts.
