ill get straight to the point and say this is my first macbook pro. im finally makin the move from PC to MAC. and all i have to say is FINALLY! but here's the dilemma, i've been reading thru the forums a couple of days now. and i think im just confusing myself more... so here it is.. i know i want the 15 inch macbook pro. and im a photographer and on a budget. is there a big diffference with the i5 and i7? 2.53 and 2.66? can i settle for the i5 2.53 ghz and still have the same performace? i know that it would be better to buy the memory elsewhere so i wont be buyn that.. 4 gig it is. update it later since im on a budget. im stickn to the 500gig. unless its better to go to the 128 SSD. and just stick to external hard disks. now the bootcamp and parallels. im thinkn bootcamp. but my question is, can i just do this manually? i mean, the macbook is already capable of this right? or do i have to make sure that when ordern the macbookpro, i let them install it for me?-- im just thinkn that maybe i cud just install it at a later time when i have the money. or that since i already have a PC, stickn to the MAC os is better. plannin to get antiglare, hi-res widescreen display for the screen. gettn aperture. is office really needed? plannin to get a mouse.. but dunno which.. and im not sure bout the antivirus. not a fan of norton. thank guys in advance. id really appreciate it if u guys cud help out. first time buyer and i wanna get the best on a budget. and plannign to just upgrade gradually.
