An anonymous reader writes "From the LA Times: 'Although Microsoft's 128 GB Surface Pro tablet is advertised as having 128 gigabytes of storage, the amount of space available to users is much less than that. That's also true for the 64 GB model. The Redmond, Wash., company confirmed Tuesday that the 128 GB Surface Pro has 83 GB of free storage, while the 64 GB version comes with 23 GB of open space. The reason for the difference: space already taken up by the tablet's Windows 8 Pro operating system and various preinstalled apps.' It's generally understood that your device won't have as much available storage as advertised, but it's usually a lot closer than this. Should device-makers be required to advertise how much storage is available to users, rather than the size of the storage media?"
