I bought a 1330 before the 1330n (ubuntu version) came out. Which means my system has an Intel 4965 AGN card. I was worried this might not work in Ubuntu, but actually it works out of the box. However, I am connecting to a "G" network, not "N". Don't know if "N" will work.
Skype 2.0 beta video works, but the builtin internal mic has problems. Following the instructions from Dell Wiki I was able to get the mic working. However, the volume on the mic is pretty low. Opening up alsamixer and playing with the "Digital" and "Capture" volumes fixed the problem for me. Now I have everything I need working on the machine! :)
