I have not tried any of those distros that you mentioned. Should though :-)

There is one thing that I did not mention. I have found that the newer kernel versions, 3.x.x have a tendency of consuming battery life excessively. What I would do is look for a distro that uses any kernel version marked 2.6.x. They seem to go easy on mobile battery life. Ubuntu 10.04 LTS uses such a kernel.

If you are using the later UIs like Gnome#, or Unity, you may experience a decrees in battery life. Also, the kernel in use could have extra functions that could drain it too.

Stick with Gnome@, XFCE or LXDE if you like user-friendly UI.

Have a look at this site:

How to Maximize the Battery Life on Your Linux Laptop

Another benefit to using "open" cloud standards is to keep service vendors competitive. The goal is to deliver optimal results to consumers. Vendors will need the ability to adapt to users needs and using opensource is becoming the primary way of doing that because it is not a "what you see is what you get" philosophy.

Can you send a link to the article that you can't edit?
