What are some sites that go into detail about why Macs accel that things generally better than PCs do? I want to send a couple to a friend who I'm trying to convince to switch over.
Put your friend in front of a Mac. From there it will sell itself.
But be sure your friend wants to be switched--or is open to the possibility. Otherwise it's just like trying to get him to go to your church when he's happy with his.
