I have Comcast for internet, telephone, and cable. Recently they implemented universal caller id. What this means is if we receive a phone call the name and number of the caller pops up on the television. But there is also a desktop application you can install which will also pop up the name and number of the caller. I didn't expect it to work on my computer without using wine. However when I attempted to download and install it I discovered it's an adobe air program and it runs just fine on my Ubuntu box no wine needed. Needless to say I was pleasantly surprised by this.
