What tools I use...
I use professional translation software, which includes MsOffice 2007, Trados 2007, Trados Studio 2009 and software for commenting and creating PDF files, as well as electronic dictionaries.
I have a fast desktop PC with Windows 7 operating system and a backup laptop for work outside my office. Of course, I also have a scanner for processing paper assignments and DVD burner, if you need the translation on CD or DVD disc. I have ADSL Internet connection and downloading big files from customer's FTP server is absolutely not a problem for me.
