Check out this video preview of some cool apps incoming for the Nokia N900. The demoed apps include 3D Roller Coaster, a game that really shows off the potential of the Nokia N900, with some amazing 3D graphics. There is also Zen Bound, another 3D game coming soon to the Ovi Store. Finally there is a quick look at the recently announced, final release of Firefox for N900, where if you keep your eyes pealed, you’ll see The Nokia Review at work. Video after the break, enjoy.

Firefox has just announced that Firefox for Mobile is now available for Nokia’s Maemo platform after only a day or two of the RC3 release. Nokia N900 owners will now be able to customise their mobile web using the add-ons features and tabbed browsing, just like the desktop browser. You can find the complete list of features after the break.

Qt is part of Nokia’s future when it comes to user interface. Check out these images giving you a few ideas on how it might look. If you have the ‘Extras Devel’ catalogue on your Nokia N900, you can find HyperUI (shown on the standby screen, the Application Launcher, the dial pad and contacts), Weather (current weather previews), MyBudget (for personal budget in several categories of expenditure) and ShopList (a shopping check list with several categories).

The Mozilla-based web browser on the Nokia N900 is by far the best mobile browser currently available on any smartphone. In the video after the break, you can see how easy it is to enable a mouse/cursor mode and enjoy free flash games on sites like PopCap Games. Bring games like Zuma and Bejeweled into the palm of your hands and enjoy the full desktop experience on the go.

Earlier this week, Nokia announced that it has filed a complaint with the United States International Trade Commission (ITC) alleging Apple of infringing seven Nokia patents in virtually all of its mobile phones, portable music players, and computers. This feud with Nokia and Apple has been going on for quite some time now, but this complaint states that Nokia’s pioneering innovations are now being used by Apple to create key features in its products in the area of user interface, as well as camera, antenna and power management technologies. These patented technologies are important to Nokia’s success as they allow better user experience, lower manufacturing costs, smaller size and longer battery life for Nokia products.

Create a personalised e-card using the Sketch app on the Nokia N900 and send it to your friends via e-mail within moments. I’d like to take this moment to wish all our readers a Merry Christmas!

This video demonstrates a cool little app called Snowtter – a twitter client bringing the Xmas spirit to your Nokia N900. It basically pulls out public tweets containing ”Christmas”, ”Xmas”, “Holidays” or “Snow”. Different snowflakes drop realistically with the messages which react with the accelerometer, so user can affect snowing speed/direction by rotating the device. The background image can also be changed by simply clicking it. Check out more cool apps from our Maemo 5 Download page.
