I've been using Sidux now for about a year so it is about time to speak up about it :-)
It worked out of the box on my Acer Aspire One (532h-2dB), acer Acer Aspire 5040 and my normal PC. With the latter I ran into some difficulty with my ATI-radeon HD3200 graphics card. I fixed this with the proprietary firmware from the ATI site, which turned out to be a huge mistake... Crashes, update problems, kernel-panic`s, floods, pestilence and fire struck me. The guy`s from the Sidux-chat-room knew aht to do and where of great help. After getting rid of the official (proprietary) ATI drivers I installed the FOSS drivers which work just fine.
One of the most impressive features of Sidux is its updating. It is a true "rolling upgrade" OS. This I have never seen in any distro I used so far and it still really impresses me every time there is a kernel upgrade!
Sidux is derived from the "testing" version of Debian (called Sid). This might make you think that it is unstable or unsafe. Sidux is nothing of the kind. It is as stable as any other distro and safty... well, that is a discussion on its own but I always install Tripwire and a firewall just in case :-)
Sidux ships with KDE as the standard GUI. This is much to my likings because I used KDE ever since 1999 and hate the looks and feel of Gnome... But than again, if you like Gnome better, you can always install that on your Sidux-box, there is no law against that! :-)
Firefox is called iceweasel and thunderbird is called icedove. Different name, but it actually is exactly the same. This has to do with some sort of discussion I don't want to get into...
As mentioned before you need to run apt in order to get some stuff working. This means that you have to alter the list files manually in order to get non-free stuff (like flash for example) working. This is also mentioned on the site, I got in trouble disregarding that advice, so for the love of god... use apt and apt only!!!
So would I suggest this distro to a complete novice? I guess not. For a complete novice there are just a bit to much things you have to know in advance. For complete novices Ubuntu still is the distro of choice.
But I would definitely
suggest it to anyone with a bit of experience (say > 6 months) working on a linuxbox.
It is safe, fast, lean, configurable, workable and easy to use.
