Because of 2 things,
I do not recommend Macs to friends and Family, i tell them to get PCs, Macs are unreliable, failure prone, nightmares.. but they do look pretty and take up less room, compared to a PC
I have had 9 macs starting with the 128k mac through a 2010 iMac and a 13" MBP. Never had apple care and never had any repairs that I had to pay for. The only problem I had was an G3 that died after 4.5 years and I upgraded, which I was ready to anyway. The only problem any of my friends or family has ever had was a HD failure on a 2010 iMac under the 1st yr warranty. On the other hand most of family and friends had many failures and problems with PCs and most have switched and are very happy.
