Ubuntu very much improved, however Ubuntu 6.06 LTS and still supported makes for an excellent server, however many are now upgrading to the equally excellent 8.04 LTS.
As far as the Desktop Ubuntu 6.10 (no longer supported) began to make in roads as far as usability was concerned. The major breakthrougn came with Ubuntu 7.04 (support ends in October) Ubuntu 7.04 was the first release to include amongst other things automatic codec detection, 3D Graphic accelaration, Beryl 3D cube or the original Compiz if prefered.
Things moved on with Ubuntu 7.10 with the first inclusion of Compiz Fusion as default. Upon release Ubuntu 7.10 was notoriously buggy with frequent crashes and many problems with the Flash plugin, however all of the problems haved now been fixed and Ubuntu 7.10 is now my personal preference.
On to Ubuntu 8.04 Long Term Support (LTS) which was released in April of this year and already Ubuntu 8.04.1 suffers from none of the above mentioned problems that Ubuntu 7.10 did. Its solid offers Wubi so you can install it along side Windows without interfering with the bootloader which appeals to far more people if they just want to dip their toes into Linux. Ubuntu 8.04.1 to install as with previous releases is a breeze with the minimum of effort. Ever since Ubuntu 7.04 has been very easy to use with far less commands to be submitted in the Terminal, with most of the work being carried out in the Synaptic Package Manager, a very painless excercise.
Ubuntu has a problem though, being shunned by Linux purists that it has become too far away from its Debian origin, in a way Ubuntu has become a victim of its own success. Some even go to the length of hating it saying it relies too much on borrowed applications from the likes of Nouvel but my claim is Canonical the developers of Ubuntu have just made better use of what is available. Nouvell have contributed much to the Linux community and continue to do so, however I do question the agreement they have with Microsoft and wether it will have a negative effect on the Linux community long term, we shall see.
The future is bright and I am currently testing Ubuntu 8.10 Alpha 3 and things look most encouraging.
Linux Mint. Many consider it to be entirely different to Ubuntu but nothing could be further from the truth. There will be many that disagree but Linux Mint is no more than Ubuntu with many applications preinstalled and wearing facepaint. This is how the releases break down along with the corresponding Ubuntu releases.
Linux Mint 3.0 (Ubuntu 7.04)
Linux Mint 3.1 (Ubuntu 7.04)
Linux Mint 4.0 which is my preference (Ubuntu 7.10)
Linux Mint 5.0 (Ubuntu 8.04 LTS)
So there you have it, without Ubuntu there would be no Linux Mint just the same as without Debian there would be no Ubuntu.
But yes things are definately looking good as Ubuntu continues to make the effort to appeal to more of the people.
