@RPiAwesomeness Ok. Would you recommend going with the element14 combo? And apart from a case, what else should I get for playing video hooked up to a TV? Or should I just buy the other stuff locally? I live in Bombay.
You need a USB power supply to provide power to the Pi. You can power the Pi via a hub, but that provides a bunch more wires and bulk to the Pi's setup that you won't need all of the time. I would suggest getting the power supply and the hub.
No, you would use the power supply to power the Pi and then connect USB devices through the hub. I only use my USB ports on the Pi for connecting the USB hub to the Pi and then connect all of the USB devices (WiFi, Keyboard, Mouse) into the hub.
You also need to make sure the hub is powered, because otherwise it'll just pull power from the Pi and then you might as well not even have a hub.
You probably could get them locally, just make sure they are from a reputable seller and the specs match. Making sure the power supply is high quality is very crucial, otherwise you risk crashing your Pi and not getting enough power.
