Hey all, I've been trying to make a decision between the 128gb and 256gb version of the 13inch MBA 2011 for school, but I don't know if the additional cost for the 256gb MBA is really justified. But I'm really worried that space will be a constraint, and also the fact that I'll probably want to use this for at least 3-4 years. I'm also looking to get Parallels along with it. Now, the thing is: I don't think I'll be using Windows much; I guess it'll only be for running some applications (Windows-based Office seem to be a requirement) and using various platforms for school that is only supported in Windows. Will 128gb be enough? Of course, I'll be getting an external HDD (500gb, or 1TB maybe) too. Perhaps 128gb users with Win 7 here can share their experiences?
