I'm sitting in that very office right now typing on my iMac and looking at my glossy screen. Looks great. Nothing sucks. No glare. Glossy is better than matte in every way, and I've had both.
Lol, another funny comment.
iMac is higher and therefore its 90 degrees to the table and you still have it in the correct eye level
MB+MPB is a laptop and unless you have it on a stand then the laptop is lower and therefore you need to tilt the screen about 100-120 degrees to get the best eye level angle.
Now, you can clearly see why iMac with glossy has less problems than MB or MBP with glossy. (considering that office has classic ceiling lighting.
