You should know that I have two XPS13 in my possession, both with Ubuntu pre-installed, so I know the economics of it.

I was questioning your logic.

Are you concerned with it's purchase price or it's resale value? You can't have both, can you?

I don't understand why you use dual boot, if you only care for Linux? Or maybe you don't? Then why complain?

The capacitive top row renders it a clear "management" option anyway, I don't understand the appeal of it for development.

I think you don't have your priorities sorted out.
