Fortunately, a lot of developers are updating their programs to support netbook resolutions. Two apps have been updated and added into the netbook friendly list of apps. The apps aren't for Windows netbooks though, sorry Windows fans, but instead for Linux run netbooks.

The other app, is Banshee Media Player which has been updated for support of smaller screens. This app however is also available for OS X. Banshee Media Player users a custom interface called "Cubano" which has been designed specifically for netbooks.
