Okay so this question has been asked millions of times but I need to know for myself so I ask. What is the best choice when buying the MBP, either 13" or 15" 2.4GHZ?. I'm already in my 4 quarter of college and the work load is beginning to increase. I'm currently running a 15.4" hp pavilion dv5 with a amd processor that drains the battery life in 1hr and half. I'm majoring in criminal justice and also in business so I know there aren't any crazy applications to run. This will be my first apple product besides the ipod touch but before I make my purchase I would like to know exactly what should I get. Being that my first laptop was a 17" Toshiba then downgraded to 15" hp which I noticed a difference but adjusted quickly. And if I aim for a 13" will there be any problems when viewing things, lets say a movie or a document. I know that there is a difference in between the 13" and 15" processors. For college all I need is the iwork or ms office so i don't need a crazy processor but then again I do rip movies and convert for the ipod. In addition I'm planning to run disc based games, like lets say gta iv. I do use photo shop occasionally so I don't know if the processors will boost the ability to run the app. faster There is more to ask... but I just dont want to end up buying a MBP that doesnt meet my standards. Like I dont want to end up with the 13" and be outdated when other prosessors are dominate. or get the 15" and not use the power that it packs.I also read somwhere that around Nov or Dec there might be a update to the MBP. might be rumors. oh and two last things. will i be needing a virus scan and should i consider getting apple care? thank you.
