Once you enter your Gmail account details (If you don't have it, it asks you to create one), it starts syncing your e-mail, contacts and calendar from the cloud. Each new e-mail you get is subsequently pushed to your phone. While the Gtalk feature is always there for instant chat feature. The Facebook and Twitter official clients on Android are as smooth as they come, while the browser is in the same league as Apple Safari, which is a good enough compliment.
So if you are greatly into any of the above then I guess it pays to get an Android.
While discussing components it is important to mention that the world orders have shifted and people walking to buy a smartphone are rarely interested in 'How many megapixel is the camera?'
Mhz (megahertz) is the new MP.
But yeah this factor is also subject to the same myth and more does not necessarily mean better. To make it simple: there are 3 main brands making processors for Android phones (Tegra not being considered).
Qualcomm, Samsung and Texas Instruments
Recommended phone based on the platform: LG Optimus One: Rs 11K.
Snapdragon 1 Ghz(QSD 8250)
But still if you must then HTC Desire is for you: Rs 22K.
The technology behind the displays is myriad, with the general consensus being Super AMOLED from Samsung being the best choice. But still this is a feature that is best selected on your own preference. More emphasis should be given to the display resolution.
1. Check out the Android version of the phone you are buying. Most phones nowadays are coming with Eclair 2.1 out of the box or even 2.2 Froyo. But some phones like Moto Backflip are still stuck in history, and are best avoided.
