The reason Windows is on top is because most computers come from the store with Windows installed. If they came from the store with Solaris installed, Solaris would be on top.
Linux is not Windows.
Expecting it to act like Windows is asking for disappointment. Remember, also, that most persons, including me, have spent years learning how to use Windows so that Windows seemed to be "computing," when all it was was Windows.
Linux is not hard (actually, having been very very good with Windows, I find Linux easier than Windows now that I am pretty good at it), but it is different.
Here are some good resources for learning Linux.
A good basic intro to Linux
. It's oriented to Ubuntu, but the information is solid. I wish I had known about it when I started with Linux five+ years ago. (I have found about dot com to be a good reference site for a lot of topics--their CSS tutorials are excellent.)
. It's Slackware-oriented, so it's very good on basics, such as permissions, file structure, and the like.
Garrels's Introduction to Linux
. Detailed and very thorough.
