Microsoft Office 2010 (Personalized)

Office 2010 will be tightly linked with your social networks. Follow this link and login with your Facebook account. It’ll make a promotional video with you as the star and your public Facebook network and photos as the co-stars! Pretty and potentially viral.

Seriously, if MS Office 2010 can deliver, it might be a Google Docs killer!

Caveat: maybe not so great if mobile access only works on Windows phones.
