Re: Skype
Skype is replacing Windows Live Messenger (which was previously called MSN Messenger). I used to use it years ago, but stopped using it.
With instant messaging from Facebook, you don't really need the Windows Live Messenger.
I have upgraded my Windows Live Messenger to Skype, but have no need to use it.
I don't have a webcam on my PC. Don't really have anyone to do video messaging with.
But do have cameras built into our tablet and my smartphone. But I won't be installing Skype on my Android devices.
