I want to know from the users of sage, their feeling on handling computations using sage on different platforms. Actually I have a windows pc and sage works by virtual machine inside it. So the computations are very slow. I am trying to compute the ray class groups associated with number fields. But the problem is: Somehow using virtual machine Sage runs too slowly, it even takes time to enter the data by the keyboard.
So I am thinking to buy a computer on some other platform (Ubuntu or Apple macbooks) (within around 1000 euro ) so that I can make some computations in a reasonable speed. I like to have user experiences on this issue.
