This publication is very useful. I'm giving you all the vote I can. A smart phone really does survive, as you say. But the information you offer here is quite extensive. I'm going to check the VPN address because in my country they just blocked the free access to soundcloud and I've been going around the internet to unblock it (I got it!) but I prefer to do more research for future occasions. It's been a great pleasure reading and hearing you.
Kind regards @cahlen
