Since I started using a computer, I have believed that there always is some “ideal software stack”, which consists of one app from each category. That I have to choose between Adobe Illustrator and Corel Draw. Later between Spotify, Apple Music, YouTube and Tidal. I was looking for the ideal app, so that I could choose and use just one. The ones, who taught me that were my devices. They seem to be designed to encourage us to use one app for text messaging, one for using camera, one for browsing the Web and so on. And it would be best, if we used the ones made by the device’s producer. Since the essence of any market is competing (i.e. on the same market, there are numerous brands, so the nature of any market is sharing it), and examples of Spotify and Netflix shows us how using some goods (like music and movies) may looks, from my point of view, for achieving our goals and doing our tasks, we should use multiple apps from the same category. Rather than choose whether to use Netflix or Prime Video, there should be a platform that enables to use both. Exactly like Spotify enables to listen to multiple albums and Netflix to watch multiple movies.
