A closer look will also reveal the general structural differences between the Desire and the Nexus One -- in theory, the latter's unibody frame should be stronger than the Desire's old-fashioned assembly, but we haven't dared to apply more force on either solid devices to prove this (unless our good friend Peter Chou gives us his blessing). That said, if you're into hardcore tight jeans, then the stone-cold Legend should probably outlast the other two phones with its greater unibody coverage on the back.To get to the battery, SIM card slot and the spring-loaded microSD slot, you need to rip open the back cover using the top slit, just like on the Hero. It's not a pleasant experience, as you'll see in the video below -- in the early days it felt like either our fingernail or the cover could break, and we'd kill for a slide-and-pop mechanism like on the Nexus One's smaller cover. Leaving this annoyance aside, both covers have similar "soft touch" suede-like textures -- certainly a warm welcome in the cold mornings, and it gives a comfortable grip as well.Underneath the cover you'll see that the camera, LED flash and loud speaker are at the same positions on both devices, except for the missing noise-canceling secondary mic on the Nexus One. Are we missing much with just one mic? Not really -- in our comparison test, we noticed that calls made on the Desire (using the same O2 SIM card) are muddled only ever so slightly, and the phone certainly doesn't peeve your ears with distorted background noise as produced by the Nexus One. Have a listen yourself:While we're on the topic of audio quality: both speakers on the Desire do their jobs well -- we had no problem with the earpiece for phone calls, and the loudspeaker on the back is, well, pretty loud and clear. The handsfree kit, however, fails to impress as it barely fits in our ears, and the sound quality is on par with the cheap iPod earphones -- it lacks bass and clarity, making the stylish three-button remote control (backward, play / pause / call, forward) a bit of a waste. Too bad this is also bundled with the Legend and the Nexus One.The Desire's screen needs no introduction -- we've already gone through the ups and downs of AMOLED in our Legend and Nexus One reviews , plus it appears to be identical to the Nexus One's anyway. Just for comparison's sake: the Desire offers sharper image than the Legend due to its higher pixel density (240 dpi versus 160 dpi), but both screens are equally hopeless when used in daylight -- basically, you'll most likely be seeing your own face while you try to watch the Trololo guy on YouTube. Let's hope that HTC will hook us up with some Super AMOLED love in the near future.For our battery tests, we followed a similar routine as we did with the Legend -- occasional web browsing on 3G connection, took some photos and videos, almost continuous music playback (with the occasional FM radio), Twitter auto-updating, Gmail push notifications and no live wallpaper. This way we managed to squeeze six hours out of the battery, which is coincidentally what we got from the Legend and the Nexus One as well. We also did tests based on a more realistic usage -- same background apps, occasional web browsing on WiFi and no or little music playback -- and this got us two more hours. Needless to say, it's best to keep the charging cable handy throughout the day.Given that all three phones have a 5-megapixel autofocus camera, we expected the same picture output from them all, but HTC's full of surprises. For starters, the Desire captures 5:3 wide still images, while the Legend does a narrower 3:2 and the Nexus One takes the good-old 4:3. Similarly, for video capture the Desire, Nexus One and Legend offer 800 x 480, 720 x 480 and 640 x 480 resolutions respectively. There's a mixture of color accuracy as well, with the Nexus One performing the best out of the three, whereas the Desire's photos tend to have a colder tint. That said, one thing that they all have in common is the weak filming performance in dark environments -- as with the Legend, you'll see reduced frame rate in videos recorded by the Desire under low light level. This could be HTC's attempt to compensate darkness by extending the exposure time, but we're pretty certain that many would prefer a smoother video.Daytime video:Nighttime video:In general, the photos were of fair quality despite the aforementioned color issues. Daytime photos were slightly under-exposed but reasonably sharp, while nighttime shots looked great but also marked with a bunch of noise lines. Close-up shots were surprisingly good (see the keyboard photos), especially when you could go all creative using the tap-to-focus function in the camera app -- something badly needed on the Nexus One. All in all, you can't expect premium photo quality from the Desire (or any HTC devices, it seems), but the camera's there if you need it.
