A lot of comments and news been scrolling on the internet since the titan’s annual developers conference and one big thing is the new update from Microsoft to its Mobile OS (windows phone 8 to 8.1). Though it is just a .1 up in its version, microsoft did worked a lot and brought major and drastic changes, bugs fix and some other improvements. Among them one is the Cortana virtual assistant, like Google Now and the other is the enhanced metro style UI, which now allows you to add even more tiles than before. Microsoft is now allowing developers to start building apps compatible with the new update. Hope, Google too in its next update may bring us some sort of updates like microsoft in User Interface.
