I have a MacBook which my wife loves. I would like to buy her a new one but we are not in a position to spend that kind of money and more than likely i need to get an Imac for the family. My questions are the following 1. Is there a previous generation to the MacBook(2008) I should consider buying used? How much should I expect to spend? My wife's needs are usually net surfing and simple word processing. 2. Are refurbished notebooks from Apple covered for a year and can I buy Apple care? Thanks in advance.
