I don't know about American Scientist, but I've got a subscription to Physics World. It's aimed at anyone with an interest in science, and they have a "No equations" policy so it's very accessible. It is basically split into 3 sections: short recent news stories, longer articles and input from the physics community (letters, short articles, book reviews, careers advice, etc...). It's good to keep up with what's happening in the physics world, and it's nice to read about interesting areas of physics that you're not going to be tested on! Probably the best incentive for getting Physics world is as an undergraduate (in Britain, anyway) you get membership to the Institute of Physics, for the duration of your degree, for £26. So, I've got a month subscription for Physics world - for 4 years - and all it's costing me is £26. Plus I get all the other benefits of the IoP, too. But, I'm not sure if this is applicable to other countries? I'd definitely look into it though.
