Since I got a bread machine on a whim, I make a loaf about every week, and I freeze half so I don't have to throw away mouldy bread. I couldn't imagine buying supermarket loaves - even fresh bakery ones. And there's something nice about the 10 minutes it takes to prepare the ingredients, and then it just cooks and fills the house with the bread aroma.

Oh, and I sold my Kindle after 1 month as I prefer to read paper books and they're cheap.

So some gadgets have a 'useful' use, and some aren't really necessary.
