Mud's my specialty -- just try my coffee if I'm not paying attention.
Skype lets you call non-Skype contacts, but in order to do so you need Skype credit, which is like 2 cents a minute, depending on where you're calling to/from. It's worth reading up on. I just use mine so I can get calls from a friend who lives in Canada who can only get to a computer for a few hours every week and whom I very much enjoy talking to. Skype on Canadian PC + Skype on my Droid = phone call instead of trying to chat/text while driving.
Plus, Skype Mobile works with my Bluetooth headset, so no tickets while talking. $50 + $85 court costs = OUCH!
