It is not very long since the current release of Ubuntu, that has a support life of 5 years. However, the next release is now in beta and it looks good. See EdgyEft/Beta - Ubuntu Wiki.
I am particularly looking forward to the F-Spot to manage photos with support for Flickr.
So how long have you guys been waiting for Windows Vista :-) This will have been my fourth major release of Ubuntu in 2 years. They install automatically and so twice a year my operating system takes a big leap forward at zero cost. Oh and sorry that you will need to buy new hardware whereas I won't.
Of course not only will an automated install work for me but because we use Sun Ray thin clients the one upgrade will update all of us at home.
Oh yes and not only all that but so far every update also gets faster. This time the startup and shutdown speed has had significant attention so much it seems they are going to drop the shutdown sound as there is not time for it to play anymore!
By the way the most enjoyable way to track lots of gossip and interesting stuff about Ubuntu is to subscribe to Planet Ubuntu.
You will notice that there is a similar button in the right hand column of "42". In case you have not noticed it then this button will subscribe you to "42": so far there are around 50 people subscribed to "42" with Bloglines (approx 1/3 of the total).
Of course you do not need to use Bloglines, there are many other newsreader applications about (Firefox can do it, Google have one and there are 1,000's of others too).
Oh and "42" also has separate feeds for the different categories (see the orange icons in the right hand column) so you can subscribe to cycling only for example. Given that "42" tends to be quite wide ranging you may prefer to only read some subjects which is why there are so many feeds.
Nowadays you can also get "42" by email, just one email a day containing all the latest posts. Use the box in the left column to get you daily dose.
