how much does Office cost, and if you have a product key for office currently can it be used to load it on? my work has licenses and i think they will support it since i will be mostly using it for work.
If you have a key you can apply it, so if you already own Office you can let your SP2 know this. I went ahead and subscribed to 365 as I wanted the full version of OneNote as well as Outlook.
It is a perpetually up to date version of any future Office version, from 2013 onward, for a subscribed fee that buys you five device seats for computers and/or laptops, and five mobile devices (outside Windows Phone, as Windows Phone has Office). The installation is all local, it doesn't run from the cloud. Only cloud access applies to syncronization and Skydrive access. Still need internet access to keep Office 365 up to date.
This would be a great route, if you can actively use all five seats for devices (such as for a family with students). It would be even better if after you unsubscribe, you get to keep your last major version of Office 365 perpetually... (don't see that happening at all).
Otherwise, if you want a perpetual, always there, non-expiring license of Office, I would get Office 2013.
Check to see if your work can allow you access to the HUP (home use program). Full pro license at a really good price. For me $15 but it would depend on your region
