IMO it looks ok but maybe not super great. it's tough to theme an entire UI! still tho i would use it except for the fact that it seems to make some text light grey, making it hard to read, especially in places where the background remains white(like in certain text entry fields in Messages or Email.. etc)
I'm torn between Eclipse and waiting for Uicolors !!
Yeah I think I will be waiting for an update or for UIColors.
