You may have seen the above picture(amongst others) floating around the internet recently. It's the much anticipated mid-range, Nokia 5800 Tube Xpressmusic mobile phone. Yes, this is the same phone you saw in The Dark Knight.

This is exciting for phone community because it would be the first Nokia with a touchscreen. And it's not a premium range model, which means many will be able to afford it.

Like many other mobile phones which sport a large touch screen and minimal physical buttons, it seems to be made to rival the wildly popular iPhone 3G. The specs are rather similar too- it has AGPS, 3mpx camera, 3.5G, Wifi, 3.5mm jack, and an accelerometer for auto-screen rotations.

But the advantage of the iPhone, like the company's Macintosh computers lie not in the hardware, but in the OS. The 5800 Tube is merely a Symbian Series 60 OS adapted onto a touchscreen device. And the same goes for other 'iPhone killers' who run Windows Mobile 6. At the end of the day, you're still stuck with a stylus.

The core of the device is flawed.

What the rival phone companies need to do is to focus on the OS instead of copying the asthetics of the iPhone without adding any true value to the device. They have to develop a revolutionary OS that is optimised for touch screen functions.

Many overlook the importance of the OS as the core of the user experience. When you reflect on it, it's not how many megapixels you've got or how big a screen you have, it's the OS that matters.

Easier said than done, but that really is the key to beating Apple at its own game.
