The Microsoft Kin One Kin Two seems to be a bit of a tough sell and that is why the two app stores have been launched concurrently with such short notice. All the more reason why they have launched them so quickly. The apps themselves look very similar and offer exactly the same things that they do on the iOS App Store. We know from long experience with the apps on the Apple Store that if you want to make an app look as good as possible on a phone with a screen of 13 inches or smaller, then a full version of it is always a better idea. This is because the bigger screens are simply not really suited to apps that are meant to look good on the smaller screens.
On the other hand, we all know how popular the iPhone is and how many tech savvy folks there are who love the large touch screen. In fact, the iPad is the very first tablet PC that is truly tablet-friendly. Therefore, the Kin One Kin Two are fairly well suited to be a store where different developers can sell their apps. It is easy to see how Microsoft can get a lot of developers onto its platform for free, without having to pay too much in the way of royalties.
The problem though is that the Kin One Kin Two is clearly not a mainstream Android device. Yes, there are many other devices that run on Google’s OS but the Kindle Fire are also a more serious competitor in terms of popularity. The two Apple iOS tablets and their many variants are definitely not going to catch on as mainstream platforms. So we can see why Microsoft is hesitant to launch such apps right now. However, they will need to make a start by launching a pair of app stores where developers can sell their apps.
