... as many people say.
This is at least my experience. Around two weeks ago Canonical released their latest Ubuntu 12.10 "Quantal Quetzal", another of Canonical's half-year scheduled Ubuntu upgrades. Since 11.04 Unity represents Ubuntu's main desktop UI.
When Unity was released I somehow didn't like it first. It was, after all, a big step away from the Gnome 2 interface, which I was used to. One of the main features suddenly missing was customizable panel's. Also the Dash was something to get used to, since the well structured main menu was gone as well. Easy to adapt for me was the left-sided launcher though.
Since I didn't want to abandon Ubuntu to this time there there were only two choices to go with: Using the classic Gnome 2 for a while or adapt Unity. I decided to do the later, simply because I thought (and that is what happened) Unity will be a long-time support by Canonical. There were also things I liked right away out of the box:
- the global menu and integrated window controls with the "top panel"
- the launcher
- the dash, after I got used to it
Something I didn't like at the very beginning (11.04 & 11.10):
- Unity was extremely unstable, especially in Ubuntu 11.04 it crashed frequently for me
- the Dash was quite buggy, sometimes apps disappeared from it and only a restart "fixed" it (throughout 11.10)
- the lack of decent multi-screen support
- Unity was slow, sometimes doing something in the OS took more time than I was used to
This got all fixed in Ubuntu 12.04 LTS! Since then I am a very happy Unity user. I didn't had any issues anymore and I feel I am way faster working with it than I was with Gnome 2. Sure, I still can not customize my panels, but the simplicity of Unity is worth it.
Recently I was trying Xubuntu for a while as well. I have seen some screenshots which reminded me of Gnome 2 and I wanted to give it a try, so I installed it beside the ubuntu-desktop. I switched back to Unity relatively fast. There were just too many things I had to configure in Xubuntu first to match my requirements, for example that Ctrl+Alt+T is opening a terminal, the dock (adding a launcher there is quite some hassle) or other shortcuts I was used to from Unity or even Gnome 2. Even after configuring everything I still felt way slower to work with. Sure, Xubuntu's main advantage is that it can run on slower machines and it has more configuration options, but for that I don't need it. For me Unity is ready to work with right after installation even it needs some tiny tweaks here and there.
So for everyone who didn't like Unity because it was too unstable before, now is the time to give it a try.
