If you're just it using for email, the web, and MS Office, the Surface RT is a better value because it comes with Office 2013 Home and Student RT at no extra cost, and it's $400 cheaper than the Pro. Office 2013 is not included with the Surface Pro, so you'll have to pay at least $100 more to get it.
There are some features missing from Office 2013 RT, most users won't notice. To be sure that you won't miss those features, check here:
