This will be my first Mac. I was searching about it. Finally i decided to buy this one: http://cgi.ebay.com/ws/eBayISAPI.dl...999628&ssPageName=STRK:MEWNX:IT#ht_500wt_1154 Sorry if i am asking stupid questions but i am new on macbooks. First of all is that one has unibody? actually i dont know if unibody is very important but they are showing it everywhere. and i asked to the seller and he said it has. I am not playing games on laptop, i will only use it for presantations and web, ipod bla bla.. not choosing the one with nvidia (which is more expensive) was a bad idea? 2 gb ram is enough for those things? is there any cons esspecially about this version of macbook? 500$ is good price for that item? Thanks.
