I'll only have this computer another year and a half or so, I don't want to invest any more in it. So I just did the math: 2GB of pictures, 3GB of music, 7GB flightsim installation, and 6GB of other files. System info says I should have 55GB of useable space (I assume this is with the OS installed) but I really only have less than 20GB of stuff that I'd save. http://www.newegg.com/Product/Product.aspx?Item=N82E16822136391 $40 If you aren't geting another laptop, you could use it in a desktop, or even in a laptop with 2 harddrive bays. Out of curiosity, what FS are you running? I assume x-plane, seeing as FSX won't run on OSX..?
