Today, I found two great reviews with a nice list of software to watch or install.
First, Linux Format Magazine published a posting announcing the releasing of Ubuntu 7.10, which included a review of the release:
Not only does the author describe his experience with installing the new version, but he also provides some nice ideas for software to install such as vlc, k3b, Kino, ardour, Google Earth & Desktop, VMWare Server, and MythTV.
Another article I found from Linux Format Magazine was about installing Slackware:
The Perfect Desktop — Slackware 12
This article also listed numerous software install ideas along with detailed explanations on how to install the system. The article also points out that the HowToForge also has other similar articles for other distributions. I haven’t tried it but the Linux Distribution Chooser sounded very interesting too.
