When you pick up a pistol in a hurry, it's a LOT easier to tell that the mag's out than whether a little lever is in the wrong position.

...if you need to use the weapon and the magazine is out of battery, in an emergency, the gun will not fire. I've read about people trying to fire a mag-disconnect weapon after it sat in their holster, and the mag catch was pressed and made the magazine slightly out of battery, engaging the safety.
If the mag is hanging out when the gun fires, it's generally going to be thrown clear under recoil, and firing a single shot may not be adequate to resolve a SD situation. IOW the shooter is probably in pretty bad shape either way.
IMHO this is less of an argument against mag disconnects and more of an argument in favor of using a quality holster and a pistol with a properly functioning mag catch. If the holster exerts enough pressure on the mag catch to eject the mag, the real problem is the holster, and the shooter needs to select a different one.

I have heard of people who like that on their bedside guns - that way you can have a round chambered and the mag out just in case the kids sneak into the bedroom in the middle of the night. Then, if you need it, you just pop the mag in and it is ready to go.
Another advantage is an additional level of comfort if one needs to leave the pistol in a vehicle while entering a "Gun Free" zone. While it's no substitute for properly locking the pistol up, the shooter can eject the mag and take it with her*, with the knowledge that the pistol can't be fired in her absence unless the thief just happens to have an appropriate magazine—the chances of which are near-zero. (*Note: Most GFZ's only ban guns—not ammunition in magazines.

A non-disconnect pistol owner can achieve the same thing by unloading the pistol on arrival and reloading it on departure, but (a) this involves additional manipulation of the pistol in a confined space and a consequent higher risk of an AD/ND; (b) there's the risk of bullet setback from shucking the same top cartridge into and out of the chamber repeatedly; and finally (c) the action of racking the slide of a pistol takes longer than simply inserting a mag and looks threatening to a bystander, increasing the risk that someone may see the shooter doing it and call the cops.
All that being said, I'm not enough of a fan of mag disconnects to insist on having them on all of my defensive pistols; I'm somewhat ambivalent about them. My point is that there are valid arguments in favor of having one.
