LG eXpo

[1] It runs Microsoft's Windows Mobile operating system, and was released in December 2009.

It boasts a crisp screen with pixel density of 291.5 ppi (diagonal) which is very close to with iPhone 4's retina display at 329.6 ppi (diagonal).

It has a fingerprint sensor which acts as D-pad and omits the need to input password as well as instil extra security for business users.

The stylus is stored externally, in a cylindrical container with a cap.
