For sure, I have it and it works almost perfectly all the time. Sometimes it doesn't work with 2007 if the file ends in x, like a .docx or .pptx, but other than that it is free and works, so it kicks ass.
Google Open Office, it's almost exactly the same as Microsoft's product except a little bit slower but... it's 100% free. If you really want the one by Microsoft Google uTorrent, download it and install it, then search for "Microsoft Office torrent" in Google and use pretty much any one of the links.
i got mine off limewire
also download a serial code program, if you have a mac it's called serial box and get the disc from your friend and take the code off that and it's free
