Nokia with First Windows Phone Handsets

Nokia unveiled a new crop of smartphones that could put the company back in the smartphone race with rivals iPhone and Android. It could also mark a turnaround for Microsoft's unpopular Windows Phone 7 software.

Nokia CEO Stephen Elop unveiled the company's new partnership with Windows Phone 7 today in the form of the Nokia Lumia 800 - a hi-tech, mid-priced handset running the latest version of Microsoft's operating system.

The phone costs £364. The cheaper, lower specced Lumia 710 model will cost just £234. Both will go on sale across Europe in November.

The pricing in particular could be crucial in putting Microsoft's Windows Phone 7 back in competition with its smartphone rivals. Microsoft CEO Steve Ballmer said that the Windows giant would cut prices to drive sales.

The partnership is predicted to capture 12.3 per cent of the European market for Microsoft over the coming year, said analysts Strategic Analytics this week.

Low-End Digital Cameras won't be Around In 2020

When Apple unveiled the iPhone 4S, smartphone competitors probably weren’t the only ones beginning to sweat. Digital camera makers also have much to be worried about. Apple’s newest phone has a killer 8-megapixel camera that takes in more light and records video at 1080p HD video. Until recently, those kind of specs were unique to digital cameras, but increasingly smartphones are taking over the market.

“Flip cameras went bye-bye and now low-end camera functions are being taken over by smartphones,” says Rob Enderle, principle analyst for the Enderle Group. Going forward, consumers will have less incentive to carry around a camera when they already have a phone in their pocket that takes quality pictures. “The point-and-shooters – and particularly the cameras that sell for under $200 – will eventually go away and be replaced by cellphones that do the same thing.”

On the other hand, Enderle predicts more expensive and high-tech cameras may have a brighter future, though not by much, as a smaller market of photo enthusiasts seek out professional-quality cameras that go above and beyond what’s offered on a phone.

Killer features from the future: Siri vs. Android Beam and Face Unlock

Both iOS 5 and Android 4.0 have a futuristic touch — and we're not just talking glowing blue tones either. With iOS 5, Apple introduced us to Siri, a voice command and search app that's almost eerily sophisticated. You can speak into your iPhone 4S and ask Siri anything you want (really, anything!) and Siri speaks the information you need — or least a quirky retort. Android has boasted handy built-in voice commands for longer, but Siri is far more comprehensive and far closer to being sentient.

Paired with the futurescape of its new look, Android 4.0 introduces two very cool little bonus features: Android Beam and Face Unlock. If you've ever used the clever app Bump to swap phone numbers, Beam is the exact same idea, but expanded. With Beam, you can tap two phones together and watch as websites, videos, directions, and apps are zapped from one phone to the other.

Face Unlock for Android 4.0 is a trick that could prove pretty useful in securing your phone from prying eyes. Using Google's face recognition technology, you can unlock your phone just by peering into the front-facing camera and having your face recognized.

Winner: Siri Both Apple and Android's new futuristic features have some inherent limitations. Siri is only available for the iPhone 4S, and isn't open to all iOS 5 users. Android Beam will debut on the new flagship Galaxy Nexus phone, and then be possible between any two Android 4.0 phones that have a Near-Field Communication (NFC) chip or sticker. Unfortunately, knowing Google's checkered past with Android updates and its ongoing struggles with its grab bag of Android makers, it's hard to say how long it'll be before the stars will align for Beam.
