So let me ask at large, and summarise the issue.
SysInfo deals with Properties (CPU, PowerSource, InputDevice)
which are named in function calls, e.g. get("CPU", callback).
The callback then receive an object that represent that property,
defined by an interface, e,g,
interface CPU {
   float load

Using the same name for the property and its interface is confusing (for 
reasons explained in this thread). So what's a good way of naming them?

Property PropCPU vs. interface CPU?
Property CPU vs. interface IntCPU?
Property PropCPU vs. interface IntCPU?
