Hardy Heron: It just works!
For the first time in my life, I installed Linux on a laptop and every feature worked out of the box: video, sound, wireless network, mouse, keyboard, desktop effects, everything! I am blown away. I’m running Hardy on a Dell D630, and I followed the upgrade path after installing Kubuntu originally with Gutsy (and then got rid of the KDE garbage). Tomorrow I’ll test out docking station and dual monitor support.
It may be time for me to start recommending Ubuntu to family and friends.
