Motorola hasn't really had much success in the smartphone market so far, but with the newly unveiled Droid, powered by Google's Android operating system, it looks like the company is putting everything into making a challenger to the Apple iPhone. The Droid combines the advantages of Google's platform with the latest and greatest developments from the mobile phone industry. First, there's the massive 9.4cm, high-resolution, multi-touch display, compared to the iPhone's 8.9cm display. Motorola has also incorporated a slide-out Qwerty keyboard, which turns the Droid into a mini-computer, and allows you to take full advantage of the big screen without having to rely on an on-screen keyboard. Access to the internet is provided via high-speed wireless technology, as well as Wi-Fi. There's also built-in GPS which gets you places via Google Maps, complete with audio cues in case you use it while driving. Together with all the usual email, web browsing and multimedia applications you'd expect from any smartphone, you'll also be able to access thousands of additional free or paid applications from Google's Android market. There's also a 5-megapixel digital camera for photos and multimedia messaging. The Droid is currently available only on CDMA in the US, but a GSM version has been announced. No release date as of yet for Hong Kong, but expect it to cost about the same as the iPhone 3GS. Pros: big screen, Qwerty keyboard, Google Android operating system Cons: bigger screen means bigger phone, have to wait for GSM version
