I am considering buying my first Mac and could use some advice about which is the better deal. I am looking at refurbs to save some money and am torn between an $899 MacBook White with 2.2Ghz but only 1GB memory and 120BG hard drive vs. a $1099 macbook aluminum with only 2Ghz processor but 2GB memory and a 160GB hard drive. I know that the processor can't be upgraded so it might be better to go with the higher processor and up the memory and hard drive later. I am torn about the value of getting the aluminum version though, which is slightly lighter (I travel a lot for work) and sleeker. I have heard complaints about the aluminum's display. My needs are not that high, as i mostly use my computer for word processing, surfing the net and watching movies. I currently have a 5-yr old dell that is practically a paperweight, so any upgrade is going to change my world. Any opinions on which is the better deal. Is it worth the extra $200 for the newer model?
