Windows 8 is out, ladies and gentlemen, but that should be known already by everyone who cares. Microsoft is no longer competing on who has the largest number of devices on the market, but who has the largest and best ecosystem.

This is where Windows 8 apps comes into play, the new ecosystem Microsoft is trying to build that may or may not prove to be worth it. The Windows 8 Store is filled with apps of all sorts, rather surprising since the numbers are well below the 50,000 mark.

To get you started with Windows 8, we have listed our ten favorite apps on the Windows 8 Store to date.

Skype - As a user of Windows 8, the Skype app should be top of your list to acquire from the Windows 8 Store. Microsoft has gotten the Skype team to redesign the application to fit the Windows 8 design style, along with making things a lot simpler for the user.

Tweetro - One of the first applications users tend to search for when using a brand new operating system, is Twitter. Well, there is no official Twitter app at the moment, but there is Tweetro, and it is more than enough to fill your Twitter needs. The design is in line with Windows 8 design style, and is one of the few apps in the Store to do it so well. The ability to load a Web page within the app and browse through photographs, is a welcoming feature.

Kindle - Paperback books are slowly becoming a thing of the past. It's all about digital stuff now, like it or not. The best app for reading and purchasing digital books, is via the Kindle app, and it works like a charm. A little bit slow when skipping pages, but that's alright. It's not bad to the point where it would remove the reader from the experience.

Clock - Windows 8 is a bit dumb when it comes to telling the time. Therefore, downloading an app simply called, Clock, is necessary. The clock on the Windows 8 start screen does not stick around, and for the user to see it, he/she is forced to bring up the charms bar. There is no way to pin the clock to the start screen either, which can be a pain for many users. To fix this problem, just download the Clock app from the store, and then pin as a Live Tile to your start screen.

Shapzzle - Games in the Windows 8 Store are not all that good. Only a few stand out and Shapzzle is one of them. The purpose of this puzzler is to change all the shapes on the board to the target shape. Sounds easy enough, right? Wrong. Shapzzle is challenging and it will have the player thinking and trying to strategize the next move, as each move is critical to success.
