For me the only utility I could possibly receive from the power cover is the life extension it would give to my sp2. Batteries are such fickle things, and since opening up the sp2 to swap it out would be a difficult feat I can see the power cover as akin to the external power packs, just with the added function of a keyboard.
I suspect the power cover will gain popularity as surface owners face the choice of either spending $200 on a keyboard, or say $2000 on another surface pro (what ever model number).
