having serious issues finding what D-Star is, what it can do, etc. I've read the wiki page and it told me absolutely nothing. If I got this radio, what can I do with D-Star?
D-STAR brings several features to the table:
First, it is a digital mode that takes less bandwidth than analog signals. This is advantageous because it allows more stations in a crowded band. Because it is digital, it allows you to combine data and voice at the same time. For example, callsigns and locations of stations are automatically displayed on everyone's radios. You can also specify specific stations to talk to and only that station's squelch will open. Because the repeaters are connected to the internet, you can easily talk to any other station via a repeater through the internet. One thing is cool is that if you include your GPS info with your transmission, the whole system automatically knows where you're at. This allows another station to automatically find you without having to know what repeater you're on (this is called callsign routing). There are other things that D-STAR can do, as well but this should give you a few ideas of the basic capabilities.
