I've read that the new iMacs won't be VESA compatible. Does this mean that there's absolutely no way to mount them at all with a monitor arm? Or just that you'll need to purchase a Mac-specific mount kit? If there's no way to mount them, do you have any recommendations on getting the monitor to eye level? Having the monitor at the perfect level is extremely important to me, considering I spend upwards of 15 hours a day working at my computer. Stacking the monitor on books isn't an option. I'm purchasing a sit/stand desk that can be raised with the push of a button, so anything that destabilizes the monitor wouldn't be a smart move.
