Hi, I am 14 and have just saved the most amount of money in my life that has taken me along time. I am saving for a 24" iMac (Which by the way is my first ever mac). I have currently got just over £1000. I will be buying at Christmas so as you can probably guess I am extremely excited. I am constantly reading about problems with the 24" iMac. Some being with the fans, some with the hard drives but most with the screen. I am concerned about spending all that money and then it being damaged. I have a few questions on this topic. 1. How safe am i buying a 24" iMac? 2. What percentage of 24" iMacs are sent back (roughly)? 3. How good are apple at refunding or fixing the iMacs? 4. Does AppleCare make a difference to the replacement process? Thanks in advance.
