During the WWDC 2011, Apple unveiled iOS5, an evolutionary operating system for smart devices, such as iPhone, iPad and iPod touch. One of the great apps that comes with iOS 5 is that of iCloud apps. iCloud app stores your digital stuff on a server over air. All documents, photos, musics, etc will be shared on all your other devices.
Smart device, such as iPhone is a must-have device. I am now starting to shift my interest to how people search information on a smart device.
