hi everyone here, I have read many threads about macboook air to find my way out but cant make a decision.So, i am asking the question myself. I am planning to buy a macbook air at my university discount which is exclusively only available in the university campus and not in online apple store. Apple store does give education discount though but not as much as my university gives me. Unfortunately, my university only have 4gb ram models available. I study business. So my requirements would be "msoffice, web surfing, itunes, iphoto, skype, dropbox, light photoshop(editing pictures of family), watching HD movies and such basic apps and NO VM. I plan to keep my air for 3-4 years. I guess that these apps would be perfect for a 4gb model but i am worried about the future like new OS and new future apps' requirements may create problems. . IF yes, then i would have buy 8gb from the apple store which i think is expensive but although affordable. SO if 4gb may meet my needs for coming years, then i would not need to waste extra bucks for the 8gb and will buy from the university. And yes, my requirements won't probably change in the future. So, please help me to make a decision. Also, i am thinking to buy a 128 gb storage version cause i have an external drive. Would i be able to survive with strategy? I live in hk. so does not have access to those BESTBUY deals ( read at many places about these new discounts in the online shopping sites). Is the screen of the macbook air is good enough for HD content. looking for some guidance.
