Microsoft sees Windows 8 as a prime delivery vehicle for its online services, so it's rather important that the company polishes the Bing apps at the heart of its experience. Accordingly, each and every one of them is receiving a tune-up. We'd argue that the biggest upgrade is coming to News: the information app now supports both RSS feeds and offline reading, quite possibly to catch newshounds who need a home once Google Reader goes dark. The refresh also introduces livelier content across the board, including dynamic maps in Weather, real-time US stock updates in Finance, 29 new leagues in Sports and live traffic updates in Maps. Travel users may be equally happy to see new content from Fodor's, Frommer's and Lonely Planet. With the exception of the soon-to-come Weather release, all the app updates should be ready and waiting in the Windows Store -- get cracking if you live in Microsoft's online world.
