My plans just changed for this afternoon, so I may not be able to test out like I had originally planned. Plus, the sun seems to have disappeared. I'll give it a shot when I get back though.
As far being under lights, generally speaking, it's not that bad. Yeah, the glossy display does get annoying, but I've learned to tune it out so it generally doesn't bother me. I'm a big fan of natural lighting, and my office gets pretty bright, and the Mini sometimes faces the window, yet I've been able to use it fine.
As far as viewing angles, I am admittedly picky. I don't have too many issues with angle, but I also like to look at it straight on, if not tilted back slightly. No issues at all with inside useage.
