Nokia has added Skype's VoIP software to its N800 Wi-Fi tablet, providing another alternative to using a mobile phone.

When the N800 was introduced at the International Consumer Electronics Show in January, Nokia and eBay's Skype division said they were working on including the popular software in the device. Now owners of N800s can finally download the software from Nokia's site.

Skype, with a claimed 196 million registered users, has expanded from its roots as a popular PC-based free calling system and offers text messaging, video calling, and low-cost dialling to and from traditional phones. There are already Skype clients for mobile devices and even some mobile smartphones, but some mobile operators try to block VoIP calls because they can eat into their voice business.

Unlike the Apple iPhone, the N800 doesn't have mobile connectivity, only Wi-Fi and short-range Bluetooth technology. So the device can access the internet in a home or office, at a public hot spot or on a municipal Wi-Fi network, but not in the vast areas covered by mobile data networks. The N800 is available at retail stores and Nokia's website for a list price of £280.

In addition to the Skype client, the new software version includes an Adobe Systems Flash 9 web browser plug-in and lets customers use larger capacity memory cards up to 8GB. The N800 has slots to accommodate Secure Digital (SD), MicroSD, MiniSD, MultiMedia Card (MMC) and Reduced-Size MMC cards. The Linux-based device also has a built-in camera and an on-screen touch keyboard and uses the Opera browser.
