I have a swivel neck G4 I-mac that I feel has some good life left in her. I have not booted it for over a year. What is the best system to run on it...Tiger or Leopard. I intend to donate it to my daughter that is limping along with an old PC. She does e-mail, surfs the internet and Word - Excel. I do still have Office X on this machine.

What do you think?
