Google release a Tech Talk on Haiku. In a nut shell, Haiku is a new operating system based on BeOS that is designed specifically for the desktop.
In the talk they mentioned that they have some bugs, but once they get those worked out, I wonder if this will be the killer OS that competes directly with Windows for the home desktop.
My biggest question is drivers. Can I load it onto my laptop? Will the wireless work on my laptop? Right now, I don’t have the time to try it, but I will let you know if and when I do.
