What is changing from iPhone to Windows Phone 8 feels? According to Christina Warren of Mashable, "When I started the Living with Lumia challenge earlier this week, I wanted to answer a fundamental question, "Can an iPhone user switch to Windows Phone 8? I'm only three days into the experiment and the truth is, I don't know. There are aspects of Windows Phone 8 that I really like and there are other aspects that are driving me up the wall."

Google Hangouts is one of the most commonly used video calling application. It is an app created by Google and is largely used by people on their android mobile phones and PC. Now, it is a little obvious that Google Hangout is accessible for android phones because the OS is also from Google. On the other hand, the positive thing is that this application for video calling can also be used for iPhone and other operating devices using iOS as well.

She added, "The most interesting part of this process for me, as a reporter, is the feedback from the community. There are lots of smartphone users on other platforms (not just iOS) that are interested in trying Windows Phone 8. The hold-up: knowing if their apps will work and if they can fit the system around their lives. That's part of why we wanted to have a Google+ hangout so that we can have a discussion about the pros and cons of switching, I can get suggestions on the best apps to try and so I can answer your questions about the Lumia 920 and Windows Phone 8."

Microsoft has mobile operating system for windows. Furthermore, Microsoft has obtained Nokia which seems it is a direct risk to Google which obtained Motorola. So, basically, Google and Microsoft are competing firms. Well, this is a big challenge which is being asked by so many consumers all over the world, Is Google Hangout could be used better in Windows Computer and Smartphones in Nokia Lumia?
