Along with a host of other goodies, this is the one that stood out the most for me.
Graphical configuration tool for X
You can now configure what driver you want to use for your graphic card, change the default resolution for all users or change your monitor's refresh rate without having to turn to the terminal. A new GUI has been added making it easy to adjust your video and monitor settings. This tool can also set up dual screen capabilities for cards that use the Xinerama mode.
Besides the fact that my first try with Ubuntu fried my hard drive and required a full rebuilding of the NTFS file system (which also enjoys native support in the new version which is nice), this new version of Ubuntu has a lot of good looking features and brings it one step closer to a mature OS worthy of consideration when selecting your operating system.
The fact that it's being shipped on Dell's now is also a very interesting move for long time hardware swashbuckler and trend breaker, Michael Dell. Just another example of a visionary company not affraid to knock over a few apple carts.
Despite my normal "white box" metality about new hardware, I'll probably give serious consideration to a Dell next time I'm in the market.
