Google Earth

What are the guys at Google thinking exactlly? I understand why they integrated a directory, calculator, dictionary, measurement converter, and forecast and directions services into the simple search engine, but now they have made Google Earth!? Basically (yes, I installed the free software, and have been playing with it for quite some time now), the program lets you zoom in on any location on the planet. No, really. For example, I was able to pinpoint my house. Also, the service will flag places such as bars, hotels, hospitals, etc. Good for a little bit of fun, but, uh ... wait -- there has to be some other reason ...

And this version is only "beta" ... what's next!? Ah! I'm overwhelmed!
