HTC Desire
The HTC Desire is essentially the same phone as the Google Nexus One, only with HTC's Sense UI overlay and a reworked chassis. Read: it's like a Nexus One only better.
For this reason, the HTC Desire has entered our top 10 at number 1, and the Google Nexus One has dropped out completely. It's tough at the top.
The Desire is a little on the large side thanks to its 3.7-inch OLED screen, but HTC has had a look at the few foibles the Nexus One has and sorted them out.
Messaging on the HTC Desire is a dream - despite not having a physical keyboard, the eerily responsive typing correction on this device is so sharp we could practically shut our eyes and mash our hands into the keyboard and still type a perfect message.
