In fact, dare we say, it's snazzier than Microsoft's own attempt? Best analogy is it feels similar to the Netflix Mobile Manager application, with kinetic scrolling and tight graphics. Of course, it only works on touchscreen devices. Sorry WM Standard.
So do we recommend? Heck, yeah! For one, it showcases a lot of hobby developer software and number two, it's all freeware. The store itself works well enough, and did we mention free?
The application does require registration, which can be done on the device or on their website. This will allow you to manage your programs via a "dashboard" interface as well as keep your software up to date.
