I have a MB that i bought a year ago. I freaking love this thing! I upgraded the hard drive and a few other things... I use this MB for everything other than gaming! I love this computer so much, but I wish I had a little more power for video editing and web design (Im just now getting into it!)! Im going to purchase a MBP in the next few weeks and I really need some advice on what to do! IS IT REALLY WORTH THE EXTRA 500 BUCKS IN THE 15in MODEL? Im not super savvy when it comes to tech specs, I just know that I have been a mac user now for the past year and I will never use a pc again! Please help me out! Thanks!
