as for why people might use it... well it's a long way off but one day you could have your corporate desktop sat in some cloud and all you need is any PC with internet access and a decent browser. You could use your own kit or any kit anywhere and still be using a company desktop. Or your own.
Personally I just thought the idea sounded freaky so I signed up for a look. Nice to see what browsers can do nowadays.
