I do not know how feasible it is (probably not at all, as the power off procedure might be hardcoded in the firmware), but here is a hack I would like to see:

Instead of displaying a blank page at the power off (I mean "hot" power-off, not complete shutdown, of course), a selected picture is shown... voila, your Reader doubles as an e-frame!

I suppose that after the unit is activated again, it should go to a blank screen and only then display the proper page, to lose some of the ghosting. You lose one page switch, but for me it would be a small price to pay...
