Mac vs PC

Which is better out of Mac and PC for an amateur, home recording job?

I have a Mac at the moment and was thinking of a Mac to go with it but turned away when I saw the cost. :shock: Do you think it is worth it for me?

I am using ACID Pro 4 at the moment-program from SONY-it is working well, but think that Mac could possibly be better for what I'm doing.

If you can, can you suggest the model of Mac I should start with?

Thanks heaps.
