WorldMate and Kayak
Busy travelers will love WorldMate, an Android and iOS mainstay that has migrated to Microsoft's Live-Tiled shores. Just forward your travel confirmations—hotel bookings, car reservations, flight details, whatever—to WorldMate, and the service will collate the details into a cohesive travel itinerary, complete with maps to your destinations. The free Windows 8 app isn't as polished or full-featured as the WorldMate apps for other platforms, but it's still very useful for getting your ducks in a row.
Need to find a flight or a place to stay? Check out Kayak (also free). (And forward those confirmations to WorldMate when you're done!)
