MAC - much much powerful and much much faster when handling large designs (RAM eating), but hv to get used to that one-button-mouse. But MAC is not so common and file supports also not that variety (like wma, wmv, rm... but still can use videolan to watch thou)

PC - more familiar, but get lag pretty quickly, rendering process much slower compare to MAC

in the end, MAC --> damn classy, wish to hv one hehehe
