If I'm reading this correctly, Xandros.
You are; furthermore, Xandros is based on Debian, which will become important later in this post.
Are there any websites that you guys would recommend as kind of a "Linux for Dummies"? Basically, Linux for those of us who've spent the last decade-plus on Windows and Mac machines?
I don't know of any all-purpose websites. However,
this Eee wiki might help you with the Eee. Learning a bit about
the command line interface would be helpful since directions are so much easier to transmit in command form. Once you're familiar with the terminal, using the man pages shouldn't be too difficult--they're a good way to get an overview of almost all CLI and many GUI programs. If you decide to enable the more complex KDE GUI,
the documentation under the section 'Application documentation' may be of some use. The
Debian forums are pretty helpful when I'm stuck on a problem.
If you have any specific topics you want to learn about or things you are trying to do, please post them--I know plenty of guides and tutorial focused around a specific subject.
Oh, it was on it right out of the box. I was just trying to install Mozilla Thunderbird last night and getting lost in instructions that were kinda familiar to the portion of my brain that remembered UNIX, but not really completely clear on how the command line installation worked.
I've gotten far too accustomed to self-installers. I'm totally not used to .tar.gz files. I'll get there, it's a learning experience.
Ah. Well, application installation/removal on Linux is usually done through a package manager. Packages managers query the repositories for a list of available packages; when you've selected what you want to install, they download and install them automatically. It's just as easy as an installer on Windows; the difference is that it's all centralised through one program/system.
Now, according to
this forum thread you should be able to install Thunderbird through the default repositories. This is by far the preferred way to do things. If that thread is incorrect, you can add additional repositories (like Debian's), or you could just download the individual packages that you need--Debian's Thunderbird, which will most likely work on your system, can be found at
one of the mirrors here; if the Asus people did their job setting up the distro, double-clicking on the file that you downloaded (called a .deb, it's Debian's version of an .exe) will install it.
Hope that helps. Feel free to throw out some more questions/problems/things that confuse you.
