Hi....its hard to tell which might be best for my new MBP Penryn..I really just want to see what the temps are ... I think I want something that is easy to FULLY uninstall without any left over headachs....is the widget easier in that regard..Pro or Nano? Which is best for the new Penryn Processors? Thanks....I have read about some issues after waking from sleep so want to avoid those obvousely.
