There are upsides to having everything on the internet. There is of course
portability. You can access everything in one location from anywhere in the
world. This is handy even in your own home where you have to configure and
maintain a home network and then you may forget which version on which
computer is most recent. If you are on business and you cross borders then
you do not need to worry about border guards seizing your computer with all
of your data or losing it. If you lose your computer then you can use
anybody's to get your data. Finally it means that you can be up and running
in less time if your OS is smaller. This all adds up. I am not saying it is
the answer to everyone's problems, but it is always good to have options.
