I am looking to buy a new mac soon which will be my primary machine and will be replacing my MBA 11.6" 2011 Base model. So i need advice which mac should i buy ? My usage is just basic Surfing, Youtube, Mail, Microsoft office. Other than this will be printing documents on regular basis & Watching movies on my tv which will be connected through HDMI. I am not looking at the PRO as my usage does not justify buying pro and carry around the extra weight as I will carry my mac everyday. So will the new macbook 12" 1.1 GHz perform better than my current macbook air ? Thats the main reason thats holding me back from going ahead and purchasing the rMB Or should I go for the latest macbook air 11.6" ?
