If you find yourself staying in a Marriott hotel later this month, you may encounter wireless charging in the lobby. The lodging outfit is set to install Qi-equipped tech from Kube Systems in the greatroom lobbies of 29 locations in October. Stations can power up to six devices at the same time while replenishing that smartphone and tablet duo without a tether. Support for iOS, Android and Windows is included, so you'll be able to leave those cords in the room when heading down for a drink at the bar. Of course, Marriott has 500 hotels around the world, so this seems to be a limited trial before widespread deployment or significant investment.
