HTC Desire S, the official successor to the Desire, joins a growing camp of Android 2.3-enabled smartphones that’s slathered over with the HTC’s 2.1 sense interface. How does it stand out amidst its siblings? First things first, while the other devices in the Desire lineup set out with niche features (Desire HD with its huge, built-for-entertainment 4.3-inch screen, Desire Z with its slide-out physical QWERTY keyboard), the Desire S was built to sit somewhere in between, offering balance between portability and performance.
