London - A mega smartphone battle is looming ahead with Nokia N900, HTC HD2 and Motorola Droid scheduled to hit the UK market in November. All three are claiming to be "iPhone killers" and unlike the umpteen number of smartphones that were launched before them, they actually promise to blow away your mind with their rich features and get you unhooked from the iPhone (i.e. if you are hooked onto one). But the billion dollar question is - which of these three smartphones is the smartest one?


First let us look at the Nokia N900, which Nokia calls an "internet tablet," a "game changer" that promises to bring the power of the computer to mobile devices.
The N900, which measures 110.9×59.8×18mm and weighs approximately 181gm, is powered by TI OMAP 3430: ARM Cortex-A8 600 MHz processor and promises ultimate multimedia experience, thanks to its 3D accelerator card PowerVR SGX with OpenGL ES 2.0 support.
The N900, which is also Nokia's first smartphone to run on the latest version of open source Linux-based Maemo 5, also boasts of a 3.5-inch WVGA resistive touchscreen display with 800x480 resolution; world-class 5-megapixel camera; WVGA video recording (at 848x480 pixels @25fps); Adobe Flash 9.4 support; support for multiple audio and video playback formats; GPS with A-GPS support; Ovi Maps; geo-tagging; TV-out; 3.5mm headphone jack; microUSB connector and infrared port.
The N900 is also road-ready for mobile internet use thanks to 3G, Bluetooth 2.1, GPRS, EDGE and WiFi support.
The smartphone also features a slide-out full landscape-oriented Qwerty tactile keyboard, full Qwerty onscreen keyboard and support for Mail for Exchange, IMAP, POP3, SMTP.
Other features include 256MB flash memory, 32GB internal storage and up to 16GB additional storage (thanks to microSD card slot); FM Radio; MP3/MP4 player; hands-free stereo speakers, accelerometer sensor (a crucial sensor that take advantage of tilting - and allows great gaming and use of the phone in landscape mode); proximity sensor (to save on battery life); document viewer and photo editor.
Nokia has also integrated its communications capabilities in the N900 and when you select a contact, you're offered a choice of communication options such as Ovi by Nokia, Skype, Google Talk, Jabber and SIP.
On the other hand, HTC HD2, which measures 120.5x67x11mm and weighs 157gm, is powered by the ultra-powerful Qualcomm 1GHz Snapdragon processor (which is used to run some netbooks) and runs on the latest Windows Mobile 6.5 Professional platform.
The HD2, which incidentally is the first Windows Mobile-based device to do away with a stylus for navigation and control, also has the biggest touchscreen practical - it sports a whopping 4.3-inch WVGA capacitive touchscreen with 480x800 resolution display.
