I need a laptop for my upcoming online mba program and the mobility..ill be using this computer intensively for at least 3 years.. Should I save 200 bucks and get the 8gb mbp15...or spend the extra and get the 16gb? Will future OS 8gb be too little? thats my main concern. I dont run too many intensive programs...(not gfx designer or anything)..maybe VM ware..im in biotech..the simple browsing..mild gaming..excel/office...online courses..etc.. advice opinion? I can wait as my online courses dont start until may..but man does it suck not having a laptop right now..(recently turned in work laptop for desktop refresh at work). thoughts? im just worried aboutt he 8gb ram..
