scooters and computers

I often see people riding electric scooters on the pavement, I think that is very cool. It would be the cheapest powered transport possible. A small battery gets you around and the cost of charging it would be almost nothing. It would be even better if they put a small seat on it. If it is legal to ride small electric scooters on the pavement then perhaps I should get one, I think you can fold them up and take them on the bus. 

I am old enough to find smart TVs amazing. I saw a man connecting a blue tooth keyboard and touchpad to an Android TV on youTube, the TV started behaving like a desktop computer, a cursor appeared on the screen and the keyboard would operate the apps. I think they get everything that made a computer in the 90s and put it on a chip, a desktop computer on a chip. Everything is there, the graphics controller, the sound controller, processor, network adapter and bios system, it is all printed on a small chip that doesn't need a cooling system. It is so small that it is concealed by the TV case, it still works as a TV. 

I need to know more.
