Amen. I'm in exactly the same situation. Took me a few years to get there but now I'm totally happy with it. I actually like the fact that I have to do everything myself. That's what keeps it interesting (and challenging once in a while).
That's indeed what I'm referring to. However, for me there is a difference between connecting to a public wifi spot and my own mobile hotspot. I do agree that knowing exactly who connects is an advantage. Just something to keep in mind when you sign up with them.
Are multiple devices connected to the same hotspot able to communicate? I don't want any random person in the coffeeshop to be able to access my machine.
