Definitely all the new operating systems will have better performance and speed while using less battery power and making better use of the processor. So how do they fare with the other mobile phone operating systems and their own previous versions? Let us take a look.
iOS 4.3 - Apple's home brewed iOS is slick and super fast. Since the previous versions have been really fast, there is not much you will notice in the new iOS 4.3. The underlying potential of this operating system, can be seen only when you use high end applications that might challenge the way iOS 4.3 works.
Android 3.0 - Android has come a long way from being a "Oh! It is just another OS." to "Wow! It's an Android." Codenamed Honeycomb, the Android 3.0 has been designed for both smart phones and tablets and it is all set to take you by surprise. If you are expecting it to look anywhere close to Android 2.x, you are wrong. It is totally different and everything about Android 3.0 is cool.
WebOS 3.0 - With two Titans in the competition in the form of iOS and Android, WebOS might look meek but it is catching up fast. Although it is not going to dethrone either iOS or Android anytime soon, those who have used WebOS have found it good to use and have had a satisfying user experience. Apart from a few changes in the user interface and little performance changes nothing much has changed in WebOS 3.0 from WebOS 2.x.
BB Tablet OS - Research in Motion (RIM) has had enormous success with its BlackBerry smartphones, RIM decide to take part is tablet OS wars by introducing BlackBerry tablet OS.
