"Some time ago a group of hyper-intelligent pan dimensional beings decided to finally answer the great question of Life, The Universe and Everything. To this end, a small band of these Debians built an incredibly powerful distribution, Ubuntu. After this great computer programme had run (a very quick 3 million minutes...or 6 years) the answer was announced. The Ultimate answer to Life, the Universe and Everything is...42, and in its' purest form 101010. Which suggests that what you really need to know is 'What was the Question?'. The great distribution kindly pointed out that what the problem really was that no-one knew the question. Accordingly, the distribution designed a set of successors, marked by a circle of friends...to ultimately bring Unity to all things living...Ubuntu 10.10, to find the question to the ultimate answer.
And with that, the Ubuntu team is pleased to announce Ubuntu 10.10. Codenamed "Maverick Meerkat", 10.10 continues Ubuntu's proud tradition
of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution." - Ubuntu Release Announcement
Clint Notes: It appears that in the tradition of Ubuntu 9.10, Ubuntu may have rushed 10.10 out the door to make the date of 10.10.10. At best, this appears to be an incremental release and there are enough issues with it such as Nvidia support which works in 10.04 but appears to have problems in 10.10, many are staying with 10.04 LTS. I have already made the decision to keep my laptop on 10.04.1 LTS. I tried the new Netbook "Unity" version of 10.10 only to find that it doesn't work on my 5 month old Dell Netbook, reverts to the "gnome desktop version." Also, when I installed it, it needed 45 MB of updates immediately upon use. When I did the updates, the machine locked up on the first attempt and then took two more "install updates" before the update process completed successfully.
I subscribe to the Ubuntu users list and the last two days have had a very active thread on how to roll back to 10.04 LTS. One should also be aware that with the release of 10.10, i586 class computers are now "persona non-gratis" (won't run 10.10); you have to be running at least an i686 class computer to install 10.10. i586 class computers are the older Pentium, Pentium MMX and the K6/K6-2/K6-2+/K6-III/K6-III+ cpu's as well as the clone chips of which there were many. You will need to stick with Lucid Lynx (10.04) if your computer falls in the older class.
10/16/2010 Update. From what I have read on various sources, including Linux-Magazine, the consensus to not upgrade to 10.10, with the possible exception of possible KDE users. Just not enough there to justify the upgrade from 10.04 LTS and it is not without problems. 10.04 is the one that works, is stable, and will be supported for a long time to come (LTS). From what others are saying about the Unity Netbook release is that it is simply not fully baked, not ready for prime time.
