Peppermint, based on Ubuntu OS and Mint OS, installs fast and takes about half the disk space as other Linux operation systems. It boots up fast at about 20 secs from the Grub menu. It is a small operating system, because it depends on cloud computing. It uses Mint Update Manager 4.0.4 which is easy to use and understand, giving update priorities. Although update manager gives no total size of selected packages and has to be restarted after a partial update.
Instead of a word processor, it uses Google Docs, Google Mail and Google Calendar.
It uses an on-line drawing program called Pixlr which is very much like Photo Shop. It is deficient on textures and other filters, but it has a large selection of brushes. Trusting all my artwork and documents to be stored on-line is still an issue for me.
It comes with on-line music, Last-FM, Pandora, The Cloud Player (which doesn't work) and Exaile (radio streams) also links to Hulu and Youtube.
Peppermint lacks many packages, many of which can be added. Much of the administration can't be solved graphically and has to be solved in terminal. You could spend many hours fixing custom settings. If you want to experiment with cloud computing, try Peppermint OS. You can even try Peppermint as a live CD without installation. I give Peppermint a 'C+', maybe a later distro will be better.
