So, what's so good about it? All I keep hearing is that it's more of the same.

It starts up faster than W7 and drains less resources. It has XBox streaming capabilities. Compared to W8.1, it actually merges touch and keyboard interfaces in a way that works really great. It also has Cortana (sadly not for us in Sweden yet) and one of the best browsers I have ever tried.

Do I need to backup my files before installing it or all my files will remain where they are?
