1. Excellent audio via the speaker, earphone and microphones.
2. Sensitive receiver minimal lost calls.
3. Amazing screen - may not have the pixel count of the iPhone 4 but brighter, larger and as accurate for input.
4. Ultra-configurable Android Operating system. With Apple on just catching up with Android (drop down menu’s, over air updates anyone?!), if you want a phone and lay it out each screen just how you want it, with the Samsung you can.
5. The huge 4.3” screen size and dual core processing of the S11 is very fast in all applications, reminding you really are using a powerful pocket computer in your hand.
6. You wouldn't let some one lay out your desk for you if you could lay it out yourself, so why be stuck with boring looking icons and nothing else? See the difference with live "widgets" giving you real time information.
7. Battery life is acceptable requiring a charge a day under reasonably heavy use. Works 100% with Exchange Server and indeed all email clients including POP and Google. Quite why BlackBerry are still selling I have no idea.
The Samsung is without question the best Android phone available today, so much so that my trusty iPhone 4 spends most of the time in a drawer at home. The S11 is very recommended, incredibly light, super thin, (think of a Rivita crisp-bread and you get some idea) and if you buy the Casemate Tough case with it (also available from the brummie boys and girls) you will have a phone that will probably last you for years.
