The iso file of SliTaz 4 RC1 is barely 34 Mb, so I downloaded it and gave this release a try.
First, Slitaz 4 RC1 has introduced some options for localization at boot-up:
Once you choose your language and keyboard layout, you get SliTaz desktop:
The browser is Midori. It has sodoku and chess as games. Out of the box, you can view & edit images with lightweight applications. Also, you can play sound files.
Another innovation is the SliTaz panel, from which you can install. In my case, installation was not possible because a file was missing. I wonder if that's because this is a release candidate.
Also, SliTaz does not come with an office suite, but it is installable, along with video players and other packages.
I'll keep testing this little distro and report more observations later.
