Something new about Office 2013 is that it is going to be touch screen and cloud friendly. This is going to be really good for people who use tablets because it will now be a lot more convenient to use. The interface will be similar to Office 2010 and there will be a lot more features like pdf conversions and easier format editing on Excel.
Overall, I look forward to using the new Office 2013.

The pdf conversions will be really nice. As of now I have to use a separate program to convert my documents to pdf. I also look forward to playing around with any new formatting features.
