Microsoft's Surface/Storage site revealed that the 32 GB Surface RT has approximately 16 GB of user-available storage and the 64 GB Surface RT has roughly 45 GB. (There's currently no comparable disclaimer yet for Surface Pro, as these devices don't launch until February 9.)
The Microsoft spokesperson I contacted about the Surface Pro storage figures added the following:
"Surface Pro has a USB 3.0 port for connectivity with almost limitless storage options, including external hard drives and USB flash drives. Surface also comes pre-loaded with SkyDrive, allowing you to store up to 7GB of content in the cloud for free. The device also includes a microSDXC card slot that lets you store up to 64GB of additional content to your device. Customers can also free up additional storage space by creating a backup bootable USB and deleting the recovery partition."
Anybody contemplating purchasing a Surface Pro put off by the amount of out-of-the-box storage you will get?
