You can download and install full-featured software, witch includes: Word, PowerPoint, Excel, Outlook, OneNote, Access, Publisher, and Lync. Every feature you will experiment in this trial version will be also available in the payed edition, so the experience will be similar.
Unfortunately the new Microsoft Office 2013, will run only on Windows 7 , Windows 8, Windows Server 2008 R2, and Windows Server 2012.
I posted below the link where you can download the software, which by the way comes in an iso format, so you can burn it on a disk and install it on your devices. :
