Finally looks like open source are getting into the nitty gritties of user interface with Gnome 2.6. Its file manager, nautilus has gone spatial! There is a preview about it HERE.

Will Open Source succeed at creating a better UI that commercial products? hmmm puts a smile on my face.

If you are interested in this stuff, also make sure you read this Arstechnica artcicle about the spatial finder. (can be related to any file managment app though)
