A reason that I responded to Flatulenters's earlier post with my question was because I am enthralled by the idea of a kind of plug and play user experience - even though I understand that command line might give a bit more control.
Perhaps I am waiting for a set up that is nearly as easy as setting up a Trezor...? hahahaha... Wishful thinking, perhaps?
Actually, we are not that far from that! There are still a few problems to solve (e.g. receiving money if one's node is offline) but it is a matter of time before someone releases a small device similar to TREZOR capable of running a Lightning Network node. I have found
an interesting tutorial on making your own portable Lightning Network node. It still requires some technical knowledge but as you can see we are getting closer to the thing described by you.
By the way, TREZOR T has got a micro-SD slot so it might have some LN related features in the future.
