I totally like the concept of creating desktops for file sharing and collaboration. I use it daily for my classes.

The UI an Design needs improvement, looks quite cheap. I would like to have a more legible font and an improved design for the icons and so on - at the moment it looks a bit like Bubble gum.

Overall: Huge recommendation, so I give 6 of 5 stars for the concept, 4 of 5 for UI - 5 tacos in total ;)
