GM. My grandmother is 72 years old, a few months ago brought the laptop with installed Ubuntu. To simplify removed all the panels and set the dock a La the Mac icons need software to "poke and earn". Well, the fonts are more exposed, of course. In the end, the bottom was 5 push buttons — chess, browser, Skype, video, off. Just to impossible. Took a week time for training, after which the grandmother began quite independently to be rummaged on the Internet. For the safety from virusni not fear, for Linux, and all sorts of terrible Windows from antivirals aren't hanging out. Now several times a week to communicate via video through Skype, sometimes asks if something is unclear.
From Windows, in my opinion, very busy interface, and it cannot be changed in a simple way. A complicated interface is a long and difficult training. Pity the elderly people, not ship them a bunch of menus and buttons.
