I love Macs. They're so touchy-feely - if you're not a read the manual type you can pretty much work out for yourself how to do something, and they just look nice and MAKE SENSE, unlike Windows (pah).
I write scripts on Celtx, which is fine, ScriptSmart worked for a bit then just died on me. I've not tried looking for Final Draft OS on torrents, is it as easy as all that?
