you don't have to pay for a +1000$ device to switch to Linux. In most cases, you can just install it in the same machine you have Windows.
It's more like replacing Samsung's Android ROM with a custom ROM. Sure, you'll have to learn new things to use it, but you don't have to buy an iPhone.
but you have the use for the very software you're using daily or medicine developments.
I play D&D from time to time, but saying that roleplaying is more important than medicine is just nuts.
