Previously, I used my Windows-PC's as long as I could, for like 5-6 years. In 2009 I bought my first iMac. My 2009 iMac 27" i5 is three years old now and my AppleCare will expire in a few months. The reason I consider bying a new iMac is that I had a few issues with my current one (all quickly resolved under AppleCare): - broken Ethernet port (mainboard replaced) - broken HDD temperature sensor (got new HDD) - defective MagicMouse (got new mouse) If I continue with my current iMac I feel I risc encountering costly repairs in the next years, especially since I read quite a lot about broken HDD's/temperature sensors. So I'm thinking about buying a new iMac because I will have AppleCare again and can avoid eventual repaircosts. Or was I just unlucky the last 2 years (all issues occurred after one year) and will I be able to use my iMac troublefree for the next 2-3 years?
