Well I did it. I installed Ubuntu 14.04 beta 2 on my main system, deleting Linux Mint. Installation was easy and I had no problems.
Now the tweaking begins. Even though I have just begun, I have run into a few issues. That is normal for a beta. Do Not Install unless you know command line and back up everything!
I did want to give a shout out to a great article entitled Things To Do After Installing Ubuntu 14.04 LTS Trusty Tahr. Very helpful.
