Tile is a great idea. It's a tiny, Bluetooth-blasting white square that hooks up to an app on your phone and constantly pings it its location. When you leave the Tile -- or whatever it's attached to -- somewhere, your phone realises, and when you go to look for it you'll have the power of the internet and Google Maps to help you remember. If that sounds good, then great -- you can now stock up on Tiles at JB Hi-Fi and Harvey Norman.
