Natural call voice, buttons that respond better, durable optical trackpad, an excellent social networking aggregation service
The Desire is yet another fine piece of work from HTC – build quality is top notch as usual, and there's little to complain about the software except for the Flash performance. Some may argue that the Desire lacks freshness since the Nexus One's already shown it all, but we'd disagree – at the end of the day it's mainly about the software and service, plus the Desire is available from more carriers to begin with (outside the US, anyway).
So, circling back to our earlier questions, for the extra cost of the Desire over the Legend you get a larger and sharper screen, faster processor, live wallpapers and video capture at a slightly higher resolution. On the other hand the Legend's button positions may provide better single-handed operation, and some may even prefer its silver metallic look and feel to go with certain Apple products (sorry, it's unavoidable), so you'd best get your hands on the two devices before handing over the cash. As for the Nexus One, despite the fancy dual-mic noise cancellation, unibody frame, touch-sensitive buttons and a trackball that glows, the only real advantages we see in it are its voice-to-text input and its slightly better camera (and this might only apply to certain batches since HTC might be sourcing from multiple sensor suppliers).
