Are you always thinking what is the difference between Windows Mobile Pocket PC, Pocket PC Phone Edition and Smartphone? Microsoft has published an article on its site dedicated to Microsoft Office products explaining the difference between each mobile device offered by the company.
"You're always on the go. Maybe you always have been, maybe you always will be. There are many different ways you can take Microsoft Windows and Microsoft Office with you. That way, when you're sitting in a plane on the snow-covered runway or crammed between two boisterous cousins in the back of a pickup truck on your way to a dreaded family reunion, you can catch up on mail, work on a spreadsheet, and even send a text message ("Dear Mother Nature: Why?").
Of course, not every mobile device can handle every situation; you need to educate yourself on what's best for you."
