Dave Elliott: I say include it. I don`t care if that is the SEO answer or not, I like to be able to work out which page i`m looking for if multiple tabs are open and company/site name is the easiest way.
Justin Y: I say if the name is already in the URL there`s no need to include it in the titles. To me it`s a waste of space for optimizing your titles. I do think its ok if you want to include it on pages like an about page, company info, contact etc.
