Compared to the direct purchase on the Microsoft Web site (99EUR), it comes with the Product Key Card off cheaper.
The reason for the transition from Office 2007 to our three computers in the family was for me:
* Outlook
* New features in Excel in data analysis / Pivot Tables
* Compared to the 2007 version significant improvements in OneNote
A useful feature for me is "Office-on-demand" - so that the Office applications can (except Outlook and OneNote) temporarily run on a computer without having to install it permant.
Generally uses Microsoft Office 2013, the so-called "Application virtualization" - which is a kind of "sandbox" that prevents that interaction between Office 2013, and possibly on the computer installed older versions of Office, Microsoft runtimes (eg Jet DB Engine), etc. comes.
Another tip:
Who Office 2013 is uncertain with respect, can only once a free Office 365 Home Premium enrichten Probeaccunt for one month under office.microsoft.com. Thanks to the features described above, you get the office again without interference from the computer.
This account you can then activate it later without any problems with the herein described product key for one year.
