I have been using Ubuntu 16.04 for last few days, and I am quite impressed with the stablility of the system. Ubuntu 14.04 has been my daily driver for the last 4 years. I did not want to switch from that version because it is very stable, and everything works without any problems. However, once I switched to 16.04 I was expecting to have problems. That has not happened yet. I did have a problem with Steam but after doing some research about the problem. I did find that I had to remove a file to get it to work. Also, I have noticed while using Handbrake with the open source AMD driver the FPS has been alot higher verses using the old AMD proprietary driver. I can copy the movies that I buy onto the hard drive alot faster. That makes me happy so far. After being impressed with 16.04, I decided to upgrade my server over to 16.04 also.
