I just want a concensus to the size of everyones partition for vista. I am going to dual boot xp pro and vista 64. I made xp 45gb because I will not be putting a lot of info on that partition. I was wondering what you thought a good size for vista will be? I was thinking around 100-120gb. I have many large programs to install like adobe CS3, office 07, etc that take up a lot of space. I want to future proof it for size. What is your take on this? I have seen some people say 20gb. Do you not put anything on this partition? That seems so small.
