I just received my Chromecast from Best Buy. I spent an hour trying to figure out how to view my Chrome tab on my older Nexus 7. I found out that it required a Chrome extension. When I tried to get it from the Chrome Web Store, I found out that it wasn't supported on Android Chrome!! How stupid. One reason I got the device was to view the tab on TV. How could Google not support Android devices?? Also, I tried to use my wife's Ipad with the Chrome browser installed and find out that it is not supported yet!! So much for using any computer, phone or tablet.
