for: - OS X - MS Office for MAC - Adobe CS3 (the whole package) i bought recently a macbook 120gb hdd. with only those installed plus skype, YM and about 12gb of iTunes library. i noticed that my available space on the macintosh HD is 270MB only. i didn't notice how much space available before i installed the other programs. so, i am wondering if those 3 programs listed above really eat up a lot of hdd space. is this normal? thanks!
