I have a 512MB Pi. I am trying to make sure I am getting the most out of it. I just downloaded a freshthe latest version of 2012-12-16-wheezy-raspbianRaspbian and installed it on the Pi. Do I also need rpi-update.? Is rpi-update meant for upgrading from the one version of RasbianRaspbian to the next?
Slightly altered question to make it independent of Raspbian version. Some minor grammar and spelling corrections. Added more tags related with the subject.
