A functioning skype client is essential for me. Lately the version that came with Ubuntu did not work for me; the sound was broken. I un-installed skype and, eventually learned that skype is now hosted by skype itself. At first this made no difference at all; it was broken, it was awful.
Yesterday, I was notified that a new version of skype was available. I installed it and now it works as it should.. No more rebooting into Windows for me.
