i currently have an ibook g4 and have had it for about 3-4 years and soon i will be buying a new laptop. But the hard thing is what i want to get either the new upgraded macbook or macbook pro.i have lots of music,pictures,and videos and alot of apps.It seems to me that my computer is getting slower and slower, i am surprised that my laptop hasn't crashed yet. so if you could just give me some help on what i should get, that would be really helpful thanks
