I'd sell the Aura and replace it with the Aura HD.....
That way you can convince your husband it's a good idea and you don't even need to wait for your birthday by explaining you still have the PW1 for a standard sized reader you can carry out and about (obviously it's not a small and light as the Aura, but it's small enough is it not?), but you've also got the Aura HD for slightly bigger and better screen.
If you want to keep the Aura as well..... good luck convincing your husband.
