Based on understanding translation, paragraph division has been changed!
Many people think that new winRT and Metro applications will not be used by commercial applications, but will only appear in daily life applications. I do not agree.
Assuming that five years later, metro applications will be widely used in people's daily lives and will be well received. At this time, let everyone go back to The winxp operation interface, it is estimated that many people are not used to it. This is like the current user, returning to the era of dos window interface in 1990.
Compared with ipad touch applications, the current win window programs are lagging behind the times. The Metro application is providing us with tools to catch up with the trend.
People spend a lot of time at work. When they feel the convenience of their life applications, they will soon think of the convenience they need at work. We believe that more and more developers will create commercial applications based on Metro.
If you don't believe it, you can check it again in five years.
