1. Google Android OS
Simply Android, Google Android OS is the most popular open-source software created by Android, Inc. and was purchased by Google, Inc. If you have an android phone, you are familiar with the Google Play (formerly known as Android Market) where you can download ranges of apps for free or for a fee. It is estimated to have 700 000 apps registered there. Too many right?
Current versions of android are as follows: Donut, Éclair, Froyo, Gingerbread, Honeycomb, Ice Cream Sandwich, and Jelly Bean. Did you see it? letters starts with D E F G H I and J. So we may assume the next version starts with letter K and guess what it is.Tadaa - Key Lime Pie. Haven't eaten it.
2. Apple iOS
Yes. Anybody knows it. If you are an iPhone or iPad user you know what I mean. The smartphones from apple uses the iOS software. Unlike Android, iOS not an opensource software.
Users that I interviewed [I'm an android user/programmer - sorry :-)] applauds iOS's performance - fast, smooth, and it doesn't slows down. Worth the price they said. But we can also consider int hardware for good performance.
