Up to 10 "devices"

I see the latest NIS 360 is available in Std, Deluxe and Premium.

Premium is for up to 10 devices.  Can someone confirm that I can put it on up to 10 PCs ?  Or do they mean max 3 PCs and 7 phones ... ?

I actually have 8 PCs so I need to know for sure. 

(In a previousversion, there was a limit of 3 PCs ...)
