Hello guys. i am planning to buy 13'' version of macbook air.will be getting the basic version with 128GB space and 4 gigs of ram. it will be my first mac. have been a windows user for 10+ years. so i need help from u guys regarding ram and the storage space. i will be using lots of microsoft word on MBA so will be installing windows 8 on it. i know mac has its own alternatives for office but i need office and no alternative will work for me. so my question is that will 128 gigs space and 4 gigs of ram be enough for both windows 8 and mac osx to run smoothly?? i am not into any coding or heavy editing. wont be downloading too many movies or songs on it too. hardly a movie or 2 per month. 256 gigs version is too expensive for me. however i can get those transcend jet drive lite sd cards for expansion. do u guys recommend those in case 128 gigs is not enough if i want to install windows 8 on it too? thanks in advance.
