Im an amateur photographer..... right now, my 15' macbook pro from 06 is a little slow and doesnt have a whole lot of HD space.... Also, when doing books in aperture I wish I could see the pages BIG!!! but....not sure if I wanna go with the 17'....Im kinda scared I'll look rediculous!! How much diff does the 8gb ram make as opposed to the 4? Whats the difference between glossy hi def screen and anti glare screen? finally...what makes it run fast!!! thats what I want badly...that dreaded spinning beachball is getting on my nerves! Thanks for any and all responses in advance..
