That would definitely be better, although you're still only capturing part of what's available, or at least a biased sample of what's available. Different form factors come onto the market at different rates - some may never be on the market, or not in an easily accessible manner (sold locally, or via word of mouth, or via private auction etc). I think perhaps that's a distinction that the article fails to make, it's easier than ever to access goods and services from all over the world, but that ease also favours mass market products. If you put as much effort into doing whatever you're trying to do as someone would have pre-internet, you probably have access to at least as much variety as they did.
