If you are looking for a tablet, you have three broad choices in terms of the operating systems – iOS, Android and Windows 8. While tablets powered by the iOS (Apple iPad or iPad Mini) are preferred by a majority of the population, Android tablets are also catching up at a healthy pace. The major problem with iOS is the closed nature of the hardware and the software. As opposed to this, Android is an open source operating system which makes way for greater flexibility in terms of usage. In the recent past, several big names like Samsung and Asus have manufactured tablets that run on Android.
