Hi All, My brother gave me his old mac that he used during college. It is a 2006 white MacBook. He took really good care of it and had a new hard drive and an OS upgrade done to it before he gave it to me. I use it for mostly e-mail, word processing, and web surfing. This is my first experience with a mac. For those who have been long users of mac, how long can I expect this machine to last? I treat it like a fine piece of china and take good care of it as my brother did. Just wondering how long it will last. Thanks.
