I just did my almost daily update, and Arch Linux happily installed GNOME 2.30 on my netbook (tomorrow: desktop), less than 30 hours after the upstream release. I don’t have words to say how amazed I am!
One thing I don’t like Linux distributions is the delay they introduce between the upstream release and the deployment to the end-user. (Not that I have much choice, since I don’t like Windows either.) The main reason I use Arch Linux is to use up-to-date software as much as possible. Traditionally I had to wait a few weeks from the upstream release to get the latest GNOME 2.xx.0 version on my computer(s), but this time Arch Linux really exceeded my expectations.
I don’t recommend Arch Linux for anyone. If you are a typical Arch user, you will find out by yourself if this is the right distro to you. But I can’t help saying I am a happy user most of the time.
