The notion of shrink wrapped software dates us I think? But to that end, I have elements of so many different native looks jumbled around in my head all the way back to amiga workbench (deluxe paint was the best), that anything without really obvious flaws like off centered text or unresponsive buttons feels shrinkwrappable to me. By my standard any of these looks is enterprise ready. I remember someone at MS looking at a gui made by a team my friend was on and mocking it for looking like it was out of tron with saturated colors on a black background in high contrast instead of "modern" 3d grey buttons. It looked a lot more like the linked UI than anything MS was producing at the time. So there is the fashion aspect of it. You want to stand out, but not too much. I think that is the aspect I'm unable to judge. If everything is in the first or second place I look, I just won't care.
