Yeah, I can't say about the glare. Some find it noticeable. It's a non-issue for me, and the same as the iMac. If you can check it out in an Apple Store, that's always best.
The height is perfect for me, actually. I do have a long torso for a woman. One issue with buying a discounted model is not having options. Apple charges way too much for the tilt/height stand, so a lot of people buy the vesa option or put the monitor on a kb shelf (which gives you space underneath).
