Off course, we don't have 3 parallel screens but it does not mean that Office 2007 are not for us :). But I am pretty sure he was working in same style before Office 2007. Oh! does Microsoft uses same version/product which they release for public? I don't think ... else they were lost in crashes :)
Anyhow, it is worthwhile to read how Bill Gates uses office.
