A browser based Windows Phone marketplace is coming along with ‘Mango’ update.
From Windows Phone blog,
To better reach customers worldwide, Iâ€™m also pleased to announce today thatÂ Mango will offer a new web version of Windows Phone Marketplace. This will enable customers to shop, share and buy/download apps and games from any PC and send them directly to their phones. You get more visibility for your apps with no extra work. The Mango Marketplace will bring several new features and capabilities that Todd Brix will be expanding upon here a little later.
Apart from the web based marketplace, Mango will also bring support for new languages,
Mango will support languages including Brazilian, Chinese (simplified and traditional), Czech, Danish, Dutch, Finnish, Greek, Hungarian, Japanese, Korean, Norwegian, Polish, Portuguese, Russian, and Swedish.
