Customers in the United States and Canada are now able to purchase some versions of Microsoft's Surface Pro 3 tablet. The Windows 8.1 device is running either i3, i5, or i7 processors, but only
the i5 versions will be available this month. The devices can be ordered starting today, and the ship date being offered by Microsoft is June 30. All of the other models can technically be ordered,
but they will not be shipping until August 1, more than a month from now.
