so i am making the decision to get a notebook and really want a macbook. however, i hate to spend $1100 on a new one when i dont really need it to do very much (we have an iMac which is our primary computer... i just basically want something for internet, itunes and photos) ... i have done a fair amount of research and noticed that ibooks get rave reviews and they are all over ebay, amazon, etc... i would prefer to not spend over $800... can anyone guide me in the right direction? would it make sense to buy an ibook off of ebay and then upgrade its features (i am not a computer whiz but my husband is). thank you so much!
