Tanglu KDE Netbook
I had seen some announcements about the Tanglu GNU/Linux distribution, but honestly I had not paid much attention to it until someone suggested that I compare it to SolydXK.
The idea behind Tanglu is that it will be derived from Debian, but it will not be subject to the long development delays and freezes that Debian goes through with every development/distribution cycle.
As such is it based on Debian Testing (not Debian Stable), and the Tanglu development team expects to provide a lot of the testing, integration, packaging and distribution of patches and updates. This is a very new distribution (the current release is 1.0), so it is difficult to predict how successful they will be at this, but at least their initial effort has been good.
The Tanglu downloads page has Live ISO images for KDE and Gnome 3 desktops, each with 32-bit and 64-bit versions, and as usual they are hybrid ISO images. Tanglu also uses Mint Install for their installer, so again there isn't much to add about that. As with SolydXK, they do not support UEFI boot yet.
Other than that, downloading, creating a Live USB stick or Live DVD, booting it and installing Tanglu is nearly identical to LMDE and SolydXK.
When I installed Tanglu KDE on my Samsung N150 Plus netbook, it came up automatically with the Netbook desktop — obviously it had detected the small screen (1024x600) and made the configuration based on that.
At the other end of the spectrum, when I loaded it on my Lenovo T400 which has dual displays (laptop and external), it detected and configured them both at optimum resolution with an extended desktop. I have loaded both the KDE and Gnome versions on the T400, and they both detected and configured the dual displays correctly.
The Tanglu base distribution does not include a few packages which are in the others, such as GIMP and any kind of photo management/editing application in the KDE version. I was a bit disappointed in that, because I am a big fan and active user of digiKam.
Of course, these packages and literally thousands of others are only one or two mouse-clicks away in the package manager.
Because of the lack of UEFI support I have so far installed Tanglu on only two of my systems (the Lenovo and Samsung, mentioned above). It installed with absolutely no problems on both of them, recognised and configured all of the hardware and everything works perfectly.

A couple of quick comments about this table. First, it is a basically random list, based on things I use regularly, things that came to mind as I was writing it, and things I saw in the menus as I was writing.
Second. the significantly older kernel version in Debian is because I use Debian Stable (Wheezy), while the other three distributions are based on Debian Testing (Jessie). Third, where there are different contents between the different desktops on the same distribution, I have tried to list them. Sorry if that makes it look a bit confusing.
Perhaps one of the most important things to consider is how updates are handled.
Debian Stable is quite conservative about updating, but it sends individual updates out whenever they are ready so there is a fairly steady trickle of them.
There is then also periodically "rollup" releases, where new ISO images are made available with all updates to that point incorporated.
For Wheezy, we are on the fourth such rollup (thus 7.4). Linux Mint Debian Edition does updates via Update Packs, which means that almost all updates are held back until a complete pack is ready and tested, then they are all released together.
As far as I know there is no formal schedule or commitment for frequency of LMDE update packs; they seem to happen about once every four to six months.
In addition, new ISO images are made available after two or three update packs, which works out to about once a year or so. But remember, LMDE is a "semi-rolling distribution", which means that even when new ISO images are released, they are just a roll-up of the base distribution and all the updates; if you already have Mint Debian installed and running, there is no need to completely re-install periodically.
SolydXK also uses the Mint Debian Update Pack mechanism, but they test, assemble and distribute their own packs, on their own schedule. That was on a monthly basis until the end of last year, but now it is on a quarterly bases (every three months).
I haven't been using Tanglu long enough to be really sure about their update processes, but it appears to be "release when ready", so individual updates will come through as they are tested and released by the package maintainers.
Finally, here are a few general tips and comments about strengths and weaknesses of each distribution:
- Debian — Choose this one if you want to really learn about Linux, not just install and use it. You will have to make the effort to get it installed and configured the way you want, to get the drivers, utilities, applications and drivers that you want or need. But when you get that done, you will most likely have a good, solid understanding of Linux administration. On the other hand, if you don't want to have to this administrative work, if you want to just "Install and Use" Linux, then you probably don't want to start with Debian.
- Linux Mint Debian Edition — This is the opposite end of the configuration-administration spectrum. Most of what you are likely to want will already be included in the base distribution, so you will have little or no additional download/install/configure work to do after the installation is complete. LMDE is about as close to "Install and Use" as any Linux distribution gets. The big question here is whether you want one of these desktops. Both Cinnamon and MATE are developed and maintained by the Linux Mint development team, and although they are spreading to other distributions somewhat, they are not as widely distributed as the "standard" KDE/Gnome/Xfce/LXDE desktops. There is a significant drawback, compared to SolydXK and Tanglu, in the Mint Debian Update Pack process, first in the apparently ever-increasing interval between Update Packs, and second in the relatively complex, possibly error-prone update procedures for the two latest Update Packs (7 and 8). In fact, this could be interpreted as indicative of a larger problem for LMDE — there may be a lack of time on the part of the Linux Mint development team, whose top priority is obviously the much more popular Mint (numbered) that is derived from Ubuntu. This is only my own opinion, and my own speculation, but I don't think it is out of the question that the Mint developers could eventually decide that they just don't have the time and resources to maintain LMDE any more. It's not likely at this point, but it's not impossible either, and if something like that matters to you, if you wouldn't be comfortable just distro-hopping if it happened, then you might want to consider it now.
- SolydXK — Very similar to LMDE, but with a choice of KDE and Xfce desktops. Again, it will be ready for productive use "out of the box" (immediately after installation). The other significant advantage of SolydXK is the availability of different versions specifically designed for Home and Business use. Choose the Home distribution for faster updating across the board, or the Business distribution to give stability and security priority over rapid updating. When compared to LMDE, SolydXK also has an advantage in Update Pack frequency and regularity. New Update Packs are promised quarterly now, and so far the SolydXK developers have been true to their word on providing updates on announced schedules. Also, although there are no firm commitments that I have seen about this, I have the feeling that even if something did happen and LMDE were discontinued, SolydXK would very likely find a way to survive on its own.
- Tanglu — Choose this one if you want to be as close to "pure" Debian as possible, but using the more recent/current packages from Debian Testing rather than the much more slowly changing Debian Stable. The idea here is that the Tanglu developers do the testing, packaging and integration much more quickly than Debian themselves do. It is planned to be a release-cycle distribution, not a rolling distribution, with new releases every six months. if you don't mind making a clean install once in a while, this can be an advantage. I always feel like things are in an overall better state when I install from scratch once in a while rather than just updating forever. But then, I guess that is the fundamental philosophical difference between releases and rolling, so you choose the one you like the best.
