    obviously aside the numbers, what will the difference between in terms of usage on the computer?

    THh difference is pretty small unless you use ext monitor with great resolution. Only difference would be in games and even that is small

    Not really, 17" MBP has the same res and it isn't any faster than 15" with 256MB

    Apple's 24" has resolution of 1920x1200, same as 17" MBP (look at Apple's site). If it's non-Apple 24", it's likely 1920x1080 so even lower res. You need +1920x1200 resolution to take advantage of extra VRAM

    In the link I linked, the top one is 15" i7 with 512MB, second one is 17" with 512MB and bottom one is 15" with 256MB

    You will not see any significant fps difference but many future games will require 512M or they will play in lower quality.

    Yeah, the only thing that would benefit from it is games. I don't know of anything else quite so graphically intensive.

    Modelling, 3D simulations, physics applications will benefit from 512 MB too. BUT read Hellhammer's link and it clearly shows you that unless you're going to use 2560x1600 (i.e. 27"/ 30" display resolution), 512 MB will only give you an advantage of generally less than 10%.
