Portable versus fixed. It is always a question we have to consider. Fixed tends, in the long run, to be more sturdy. Portable offers the power of movement. Of course, the stronger you are or the smaller you are, the definition of portability changes radically. But it is something that you have to consider when buying technology. Will I never need to move it? It is part of the consumer functionality matrix. For enterprise systems, the choices are easier but normally not something that anyone has to figure out. Usually, a major group in the organization decides whether we are portable or fixed. From there, each of the users already knows. But in the consumer market, that is something we have to do ourselves.
The conversation of portability starts with Functionality and capabilities. Let’s talk about what that means. The first piece is the Functionality you are looking for in the device. For example, a camping solar array that is 100 pounds or designed as a fixed solar array won’t really help you camping unless you connect it to an RV. Portable solar power systems have to be around 3-10 pounds to be carried and moved about easily. Transportation of the device is a choice in that matter. Putting it on an RV, then it can weigh more overall. Carrying it to a primitive campsite, it has to be something you can easily carry in your backpack. I wouldn’t say I like having more than 24 pounds in my backpack, but I don’t hike to primitive campsites.
Capability refers to how you use the device and again focuses on the concept of what you need the device to do. For example, a Swiss army knife is portable, but you wouldn’t saw down a tree with one. It would take a long time. Chainsaws are better for that, but if the portability factor fits in your pocket, the reality s that the chainsaw won’t fit. I have thought about a matrix for a long time; for example, portability for me changes when my back hurts. That reduces what I am willing to carry. Portability in the summer for me is different than in the winter. I am willing to carry two hand warmers, a heavy coat, and huge gloves in the winter. In the summer, I try only to carry a single water bottle.
Just my early thinking on the concept of portability!
