The new Maemo 5 software in the Nokia N900 has some surprises, including Skype baked into the operating system. Sweet! This will allow you to make free calls using the uber-gadgety Nokia N900.
What else is new? Well Maemo 5 will update over-the-air (OTA), so no more connecting to a PC just to do a software update. It also sports a 5MP camera with Carl Zeiss optics for a high-quality camera that iPhone users could only dream about. You can also zoo, crop, remove red eye and more on the Nokia N900.

The Nokia N900 is Linux-based and so it feature a full-fledged browser that is more powerful than your typical mobile browser. For instance, it can play YouTube and other Flash videos in the webpage without having to launch a separate player like the iPhone has to do.
Within the Skype application you'll notice that your Skype contacts appear with their online status in the Nokia N900 address book. You can call, or IM over 3G and WiFi. Previous calls and instant messages on Skype appear in your conversation history. Smilies and other emoticons are supported in IM.
