Works flawlessly, the core i3 option with 4 gb of ram is just a perfect combination. Perfect for mid-level tasking and the graphics are not to shabby for an integrated video card. 720 P on this 14' screen is quiet good. I can easily be watching a video, open up 15-20 tabs on the browser and stil have extra processing power to do anything else I need. As for the battery life, anywhere between 4-6 hours based on the level of processing and screen brightness.
Hardware is amazing for the price, really good performing regardless of the OS.
The only reason why I am not giving it 5 stars is due to the fact that the first recommended update to pre-installed Ubuntu 11.10 messes up display driver (flashing green lines on top of the screen after update and reboot). Had to rollback using recovery media and then de-select kernel and xorg packages before update to avoid issue repeating itself.
