Which platform is best for different tasks?
With so many smartphones available, which one should you plump for? We test four handsets that use different operating systems to see which areas they excel in.
Music playback quality
The iPhone's sound quality was notably crisper and cleaner than the other three smart phones. It also has a built-in 3.5mm headphone jack, which is the standard size for stereo headphones, so you can enjoy your music using your favorite set of headsets. The Nokia E71 also has bright, crisp audio playback quality that was just a hair lower in quality than the iPod. However, its headphone jack was the smaller 2.5mm size. It came with a set of in-ear headphones that sounded better than the headphones included with the other phones, but that's not saying much. If you want better sound quality with the E71, you'll need to buy a Bluetooth stereo headset.
The BlackBerry Curve has a standard 3.5mm jack, but its playback quality was not quite as crisp as that the E71's or the iPhone's. The HTC Touch Dual had serviceable audio playback quality but, strangely, it doesn't have a jack of any size for plugging in a headset. Rather, it comes with in-ear headphones that plug into the device's mini-USB port. The quality of those headphones isn't very good, so music fans will have to depend on Bluetooth stereo headphones.
With its built-in application for YouTube, the iPhone was clearly the champ in this test. Playback quality was flawlessly crisp and smooth. And it was the only device that could play back the video in landscape mode, providing a more spacious viewing experience. Video playback on the Nokia E71 was strong, with crisp clear image quality and no distortion or jerkiness, although the screen is smaller than the iPhone's.
The HTC's playback was poor, however. Images were distorted and sometimes were halting and jerky. The BlackBerry Curve 8310 does not support playback of YouTube videos, although the higher-end Curve 8330 does have that capability.
