I upgrade my ASUS eeepc to the new Ubuntu Natty Narwhal and am still getting used to the new Unity interface. Overall everything seems to be working find, but I had a problem using scp to copy a file from the netbook to another host. The network would just drop after 60+MB copied. ifconfig and the network manager applet (nm-applet) all showed nothing wrong and there was also no sign of trouble in the logs.
sudo add-apt-repository ppa:kernel-ppa/ppa
sudo apt-get update && sudo apt-get dist-upgrade -y
That got me up and running much better.
