Historically HTC have manufactured phones for the Enterprise market but since the birth of the smartphone they have been right at the forefront of market. For the most part they have chosen to focus on phones with Android OS but the HTC HD7 & HTC 7 Mozart both have Windows Phone 7 OS. HTC love to add their own custom software to their mobile phones and because of Android’s openness, their Android devices are pretty customized indeed. This latest iteration of their custom user interface for Android, called Sense, is really starting to push it. They’ve customized almost everything there is to customize, the home screen, the framework, widgets, the standard apps, and more.
