A lot of people are complaining about the lack of apps on the Microsoft store. As the drive of windows 8 and the windows phone integration continues you can expect that more apps will appear.
I personally feel that the lack of quality and lack of functionality within existing “branded” apps is a bigger problem.
The same apps in Apple and Google are more functional than the windows versions. Same app. Different functionality.
Early adopters will not like this. Not at all.
