Yes, the swivel LCD is useful for overhead and otherwise hard to get shots.
The EVF presents shooting information and allows you to make changes on the fly without taking your eyes off the scene, using the "quiet" button on the front or function button/quick menu on the back.
WB and exposure bracketing are fast and incredible, something you have to try yourself.
Built in HDR Paint mode gives excellent results at the low and medium setting. Other special effects are useful such as the auto panorama which can be set to a standard width or ultra wide. You can pan in vertical or horizontal camera orientation, the former giving you a really large and wide shot. The stitching is excellent and better than I usually get making a manual panorama shot.

What do you think of the A99 @ ISO 12,800 - see images below. My comparison showed it to be about equal to the D800 at ISO 12,800 and the D600 has about a 1/2 stop advantage over the A99 at that ISO. NR set LOW for first shot of the tulip and NR OFF for the others.
We do not use the A99 for video and do not consider SLRs good video cameras and that includes all of the Nikons. Much better video can be had with an inexpensive Sony Handicam. Our opinions are not shared by Imaging-Resource's review:
"Sony has a lot of experience with video recording, which they bring to bear in all of their digital cameras, from entry-level models to the impressive A99. The Sony A99 kicks the line's video chops up another couple of notches into true pro territory, though, with 1080/60p recording, excellent audio-recording option, and the ability to output uncompressed video through its HDMI port to external recording or monitoring devices. At the same time, the A99's video image quality is great, and its full-frame sensor produces excellent results in low-light situations."
Another bonus for me is the availability of Zeiss glass that will autofocus with the camera. The performance of the 85mm f/1.4, 24-70 f/2.8 and the 16-35mm f/2.8 are pretty much at the top of any lens comparison.
