Ok then why is it built into IOS and ANDROID, if developers can make it themselves?
When you think about it and you see current trends in the mobile os' today, most people download third party apps for tools like stopwatch. Why really spend time and money on a function that a developer can make for your company indirectly without cost. It allows Microsoft to focus more on important issues.
Granted Microsoft has been slow on other features, but they have been going through some transitions within the company. Now it seems that Microsoft has their two feet on the ground, things may possibly move faster.
This also allows growth within the dev. community. It gives people the chance to be creative with code, which surfaces talent that Microsoft can use. Rudy Huyn would be an example of this situation.
Yeah, it would be great if there was one, but not necessarily needed. Theres an app for that ...
