BWT, objects you thought you didn’t need but can no longer live without

Mine are lint shaver (makes your cashmere happy), e book reader (for trips, small handbags and reading in the dark with someone asleep next to you), Samsung frame tv (wait, that's not actually a painting on that wall?!). What are yours?

(Doesn't have to be for the home, flair is more general tasteful consumerism)

Edit: Wow! So many things I now want. Thanks so much for all your contributions!
