If you are planning to buy yourself a copy of Office, you don’t have to postpone your purchase decision – just buy a copy of Office 2007 today and you can later upgrade to Office 2010 for free.
To qualify for the free upgrad, you must purchase and active your Office 2007 suite between March 5, 2010 and September 30, 2010.
The other good part is you won’t have to uninstall your copy of Office 2007 for running Office 2010 – the two versions can co-exist except for maybe Outlook.
