I haven't since my teens, but then I agree there is little point these days when you can find out all the reviews online and demos are available through Xbox Live & PSN. Not to mention, the top sellers seem to be the Official Magazines, which I would imagine these days are still biased.
A friend bought me a copy of Edge while I was in Hospital a few months ago, and that was a good read, because like others have said, it's a more adult read, and looks at the industry as well. I don't buy it often, but If I'm going away anywhere, it would be the one I pick up.
