Running Windows programs on Mac: dual boot or virtual machine?

[cosmik debris]

The main problem of virtual machines is that I will have to install Matlab and Excel again on virtual Windows (I will lose memory for nothing) or I need some way to share the output file from virtual Windows to Matlab and Excel on my mac. I don't know if there is an easy way to do that

Virtual box allows you share folders between operating systems, there is nothing to it.
