The Skype client will let users make nearly-free calls to other Skype users, landlines and mobile phones whenever they are connected to a Wi-Fi hotspot. The client includes an experience that mimics the desktop, complete with chat and presence controls.
Nokia also added an Adobe Flash 9 browser plug-in, which make the Interwebs a whole lot more fun to browse. Any Flash-driven media embedded in Web sites will be supported.
The storage capacity of the N800 has been boosted as well. While it accepted microSD cards up to 2 Gigabytes before, it now supports the SDHC standard and can handle cards up to 8 Gigabytes. That means a 4x increase in the amount of media you can bring with you while on the go.
Lastly, some software tweaks to the way the OS works when connected to Wi-Fi hotspots are helping to improve battery life of the device.
These all add up to a richer experience on the N800.
