I'm purchasing a new computer for my office, and the new iMac is on the top of my list. My concern is the all glass screen. I use my MacBook Air in my office a lot, and the glare off the windows gives me issues all the time. I've had to sit at a different angle or lower the screen angle. My office has three windows and is very bright (two windows face east). Does anyone have experience with using the iMacs in rooms with plenty of light? I'm afraid with the issues I have already with the glare from my MBA that an iMac will be worse. Thanks for the feedback.
