Went from Jaunty to Karmic on a Dell Mini 9 (both were the Netbook Remix editions) and was greeted with no wireless and no microphone in Skype. The former is a documented issue with the Broadcom drivers and has a fairly straightforward workaround if you're within reach of a wired ethernet connection. The latter appears to be a problem with Skype 2.1.0.47 (current version in Medibuntu for Karmic, and a "beta" no less) and PulseAudio. So far, the workarounds for the latter appear to be to downgrade Skype or remove Pulse.
