hey guys! I've been looking into getting my first MacBook pro for about a month and I'm finally getting it on Sunday. I'm getting the 2.5 ghz 15 inch MacBook pro with 4gig of ram. Since this is my first mac I just wanted to know what I should do as far as helpful apps, making backups of everything, external hard drives etc. To ensure I do everything right while its brand new so I get same amazing years and functionallity out of it. Thank you!
