Unlike with its smartphones you can't make phone or data calls over a cellular network with Nokia's tablets, however. Rather, they're designed to access the Web (through its Mozilla browser with Flash support) and send and receive e-mail, for example, over Wi-Fi, as well as perform voice calls using VoIP (Voice over Internet Protocol)—with Skype support.

Download a software client get onto Boingo’s network of hotspots for $7.95 a month.

You can also connect to the Internet through a wireless Bluetooth connection to a mobile phone or smartphone. The integrated Bluetooth supports A2DP, which means you can use wireless stereo headphones to enjoy the N810's multimedia features.

So what's new in the N810?

The most noticeable addition to is the addition of a full hardware-based QWERTY thumb-keyboard that slides out from underneath the display. It also sports an update to Nokia's Linux operating system.

Another major new features is the integration of a global positioning system (GPS) chip to support location-based services like Wayfinder's mapping software (with points-of-interest), which is now bundled.

The N810 weighs 7.9 ounces and measures 5.0 x 2.83 x 0.55 inches; far smaller and lighter than a notebook but larger than your typical smartphone.

Additional features include a VGA webcam, an ambient light sensor, stereo speakers, a microphone, integrated desk stand, a hardware lock key, 3.5mm headphone jack, and the same size 4.13-inch and WVGA (800 x 480 pixel) resolution touch display as the previous model. The screen is supposed to be 20 percent brighter, however.

The N810 runs on a 400MHz processor, 128MB or RAM, and 256MB ROM. Although it includes 2GB of internal memory, you can greatly increase its storage capacity through both miniSD and microSD cards.

Battery life is supposed to be 4 hours when playing moves or accessing the Web. (That is with the display on and or with WLAN active). It bumps up to 10 hours when listening to music exclusively.

Nokia intends to release the N810 Internet Tablet by the middle of November for $479
