...to know before I get it? it's an older model, but what does that really mean? It has 2 GB, 160 Hard drive space. Not sure what the other specs are. I looked on the apple site itself and I didn't even see the option for 160 on the hard drive space at all. The main use of the laptop will be for typing up papers, research on the internet, i tunes, skype, storing photos. Will I be able to have multiple windows open without any of that slowing me down?
