I use a macbook air myself with no problem. However, I recently bought a macbook pro for my wife and what a disappointment! she uses her mac for communicating with members of a volunteer group and because none of them can open her attachments has had to go back to using a Lenovo notebook. What a waste of au$2,200. I wish I had known of this problem before lashing out a lot of money on the mac. Anyone want to buy a cheap mac?
