I brought home a new MacBook with the super drive this week and an upgrade to 2GB of memory. (So Cool!) I did this instead of replacing the hardrive in my 2004 PowerBook G4 for the second time. I am wanting to do whatever I can to protect my MacBook. I live in an RV and sometimes the electrical systems in the parks are very old and problematic. I am not sure if the failure of Powerbook was related to this or not, but I do know it could be. I have heard you can buy a product to protect your equipment from bad power that is a step-up from a power surge strip. If anyone has any suggestions or brand recommendations please share. I will appreciate any input.
