When I watched the film Memento, I found myself thinking 'holy shit, I'm not quite far away enough from this...'. No tattoos yet, but one could write a book on the stcky pads I've laying around.
As a bit of a luddite, e-ink is one of the few modern wizbangs I'm enamored with. It's so damn nice I take it as an inside woosh joke that it isn't everywhere and available without pawning my organs.
