A new Long Term Support big release of Ubuntu is in a week and I'm already successfully running the beta. I accepted by now that trying to escape the Ubuntu gravity well just isn't doing it for me personally and I need a system that just works. Prior to Ubuntu Hardy I ran Debian Sid for a while, but after not being able to boot after the first dist-upgrade I swiftly switched to Ubuntu.
I gotta say I love the experience by now, especially with Firefox 3 (beta5 included in Hardy beta). It's much faster and responsive and I love some of the nice details like having less dialog boxes asking you questions like "do you want to save that password", but rather does more with those bars at the top. It seems they really made it no-frills this time. It is all logical, easy to use and intuitive.
And the rest of the distribution also seems to reflect this. GNOME is getting really good lately. Now there is, to some extent, even better support for remote file management using nautilus, so for quick edits or uploads on my VPS server I no longer need to be using konqueror all the time.
Anyway, did you try it, what did you think of it?
