Hello everyone I'm about to purchase a new Macbook Pro. However I dont know which of the macbooks will fit my needs. I prefer the 13" because I like my laptop to be small and portable but I'm not sure if it has enough power to do what I need Here is the list of what I need my laptop to do )Using iMovie 09 to edit home made movies (SD and sometimes AVCHD) )Using iTunes )Using iPhoto and Adobe Lightroom to manage my photos )Work with RAW files within iPhoto, Photoshop and Lightroom (No heavy editing, just basic stuff) )Microsoft Office )Web, Mail, iCal, Address Book )No games Is the 13" Macbook Pro with nVidia 9400 capable for my needs? Does it support the upcoming Mac OSX Snow Leopard with all of its features? Thank you in advance PS: Is there a lot of difference in terms of speed between the 2.26 and 2.53 processors? Is the speed difference really noticeable?
