hey guys, im looking forward to buying a macbook pro 2.5ghz. the 2500 buck model. i am a dj and i will be using it a for audio production and also for rane serrato. i currently have a hp q6600 quad core running 3gb memory and vista i think its a wicked fast computer! im hoping that the macbook can get the same speed or even faster?. i will put vista on it in the future or maybe until i manage to afford the vista disc after i get the mac. i did some research and learned that theres only a few differences btw the 2500 and 2000 buck model. is there a huge difference in performance? i am young around 17 years old and 500 bucks is a huge deal to me. but i am getting lucky because i think i can get the macbook pro at guitar center on a credit card 1 year no payment and intrest free i have bought most my gear that way. also how much space does mac osx and all the other progs take up on the hd? i keep forgetting to check this at the apple store. i am looking for some advice from some the guys on these forums because i have never owned a mac but they look very ******** free and reliable which is important to the work that i do. i am also going to purchase rane sertao which is a djing program for about 540 and i figure with the macbook pro plus that would be around 3200$ but if the basemodel is suitable i can end up spending a lil less maybe 2800 or so. thanks for the help.
