After yet another flawless Ubuntu upgrade, I  am finally seeing why there is a big hype regarding Unity. Prior to this upgrade I was hesitant in upgrading to Ubuntu 11.04 because of the negative reviews Unity was getting from different podcasts, however after a full day after the upgrade and a few hours using Unity, I have to say that I completely love the new Unity UI. As a joint Mac OS X and Linux user, I feel that the new Unity User Interface is a perfect combination of both worlds. Though I might say that I’m somewhat concern that Apple (given the record they have) will end up suing the Ubuntu project given some similarities Unity has to OS X.

Overall I think the new Unity Ubuntu desktop change is well worth it, and unlike the KDE4 upgrade from KDE 3.5 a few years ago, Unity seems to be rock solid.

The only problem that I had with Ubuntu 11.4 was getting my wireless card to work on the new version, lucky I stumble across a German forum board where somebody successully got it to work.

 
sudo rfkill unblock all
echo 'options acer_wmi wireless=1' | sudo tee /etc/modprobe.d/acer_wmi.conf

reboot and wireless should start working!!!
