A non-magical quarterstaff does *not* work as both.
A non-magical [Implement] Quarterstaff works as both.
Identical was perhaps too stronger a modifier. In the hands of a wizard, its a Staff he can activate for a minor arcane shield (Or whatever fluff you use)
There is still no requirement to make it cost more. Hell, the Wizard could spend a round investing the same arcane energy he uses to power Mage Hand, into the staff, therefore adding the Keyword [Implement]
The important part is, if it doesn't have the Keyword, its not an Implement. If a staff has the Keyword [Implement] it is also stated to have the Keyword [Weapon]
