it's not all about looks, aluminum helps with heat transfer and the like. macbook is probably the apple model that makes the least sense, as most people paying $999 would just pay $1199 for much better specs, a backlit keyboard and an aluminum body but i suppose it makes sense in one way. i suppose if you prefer plastic, want to save a couple hundred dollars, and still want an actual mac, the the macbook is for you. you can get a refurbished model for $850 and then upgrade the ram and hdd to 4gb/7200rpm 250gb for another $95 or so, totaling about $945, which is less than a new entry level. then you have a 2.4ghz/4gb/7200rpm mac with an nvidia gpu which isn't too shabby. something to think about if you are considering the 2010 model and wouldn't mind getting a refurb.
