I live in India and I will be going to a new school soon and it is mandatory for me to have a laptop. I do a lot of social networking, little gaming like black ops, watch movies and do photo editing. My options are pre configured MacBook air with 256 GB SSD 1.8 GHz and 4 GB ram that is soldered. Or a MacBook pro retina 13 inch with 128GB SSD 2.5 GHz and 8 GB ram. Or a MacBook pro with 750 GB hdd, 2.9GHz sand 8 GB ram. All of these cost the same. I am also considering a MacBook pro with base config to save money. I need the laptop to last for atleast 4 years so I am concerned about the ram on MacBook air. Please help. Thank you. Fanboy8153.
