Anyway, going back to the HTC Desire, it's a great improvement on all HTC Android phones, not only on the Nexus One. Specifically, HTC made the Desire with four hardware keys and an optical mouse. They did away with the touch-sensitive panel buttons and trackball of the Nexus One and other HTC Android phones. Inside and out, the HTC Desire is an advanced Android smartphone worthy of competing with other phones made by other companies. It has Android 2.1 running, a large AMOLED screen, HTC's later version of the Sense UI (if you are not so much into the Android Interface), and a multitude of other great features and specs that make the HTC Desire worthy of the extra bucks you will have to be paid for getting it instead of the earlier HTC Legend.
