I going back and forth between the Tab Pro 10.1 or the Ipad Air 16gb... on one side I like the feeling and look of ios.. my phone currently is a Galaxy S4 and run great but it's not jaw dropping in term of menus or look. My mom have an ipad Air and looks and feel great... the only thing that is keeping me away from it is the lack of memory expansion... my budget is around the 16gb model and is not enough... with the tab pro I plan on buying a 64fb memory and copy movies and videos from my computer to the tablet... few questions regarding this tablet: does the galaxy pro read divx coded? .mkv?, .avi, etc? I know on the ipad you would have to convert movies to mp4 in order to play it.... another questions is about the performance... is the performance on browsing, apps, youtube, etc... similar to the galaxy S4 or better? is the tab pro a good option to replace the use of a laptop (I'm talking about basic stuff like email, browsing, watch movies, music, etc)?
