Hey guys, I am about to take a tablet next month and I have put an eye on the ipad mini with retina or the ipad air. There are a few questions I would like to ask about iPads. 1. Is there any way to get rid of the black bars while watching movies? Is there a way to stretch the video to full screen without cutting part of the image? Like some other tablets do. Like watching with another player. Also can .mkv movies be watched with cyrillic subtitles? 2. Is the difference between the colour reproduction noticeable? 3. Are there any problems with syncing the device with windows 8.1? 4. Do you think the iPad mini retina/Air is better than the galaxy tab pro 8.4/10.1 for mixed use? 5. How is the battery life? Share your experiences. Thanks in advance. PS: I am a first time iPad user so I don't really know about iOS.
