Keeping all of your digital devices together on short trips can be challenging today. With all of the accessories that are necessary to fully utilize them, clutter is a real issue to have to deal with.
Even the most perfect and conditioned system of organization will be challenged if you have to carry extra parts to boot. Actually only some of the traveling phone company salespeople will have to do this as they will need to be able to provide samples of the mobile phone parts to prospective associates. This is the way it is in our company anyway and the system seems to work well according to the salespeople I have spoken with. The common responses are that at least by having samples of the parts on hand, they never have to leave their prospects in the dark.
Other companies may only uses factory seconds or parts with visible dings on them to use as displays. Not our company though, they seem to prefer to go all out when it comes to what the salespeople have access to. Things have been this way for a long time now too. This includes batteries, chargers, SD cards and an enormous variety of what the prospects will most likely want to see ahead of time. Organizing this is key to a good presentation, and this is precisely what the folks who do this everyday are taught right from the beginning.
