Hello, Ive decided to get the 13" Macbook Air, with 8gb ram and i7 processor. (could change to i5, not sure yet) My main thought was to get the 128gb ssd and a 1TB external HDD. Now I looked around and I think maybe 256gb will be better, but costs almost 200 more. Otherwise I'll buy a external HDD for 75. So to give some examples. (for ssd 128gb, music/movies etc are on hdd) - Ilife and Iwork - Steam (15gb) - Games (25gb) - Bootcamp windows 7 (?? gb) (think 15 for install) (only for games) - Adobe reader and other programs (10gb?) - School documents (10gb) - Maschine software (5gb) (will put all files on external HDD, install on ssd) So quick at up, makes it 80gb, and maybe I forget something. can steam be installed on external HDD? then it will be 65. Will that be enough for coming 5 years? or will the 180 be better for the 256gb? Like to hear your opinions, or maybe something I forgot to include in my calculation.
