Here’s a new free app for any of your apple devices (iPad, iPhone, etc). You can get Smart Office 2 for your device for free! This app makes viewing, creating, editing and sharing Microsoft Office and other documents on the move even easier through a contextual interface; drag and drop editing; sharing to email in original or PDF format; and sharing to Drop box, Box or Google Docs.
You can even print from this app too! It will link to thousands of wireless printers from 34 manufacturers including HP, Epson, Canon and Samsung. However, not all printers or network configurations are compatible, so you keep that in mind.
