Hello,
I tried out the Ubuntu 11.04 64 bit edition on my system and was amazed at the new UI. It looks like a mix of Android, Apple and Ubuntu-Netbook-Edition. The developers have thoughtfully eliminated the horizontal bars and put the menu vertically on the left had side. Nowadays with monitors short in height but stretched wide, there is surplus space on the vertical sides. There is this new Libre-Office. I wonder if there is some dispute with OOo? The Apple like feature is the permanent menu bar that adapts into the open application's menu bar and back after the application is closed. As time permits, I will install it in my system.
