I subscribed to Newsweek for a couple of years, but then when it was time to renew again, I let my subscription lapse.
There's nothing wrong with the magazine, but I just had too much to read and it didn't seem essential.
I already read a lot of news online and in the newspaper, so Newsweek usually wasn't telling me stuff I didn't know anything about. What the magazine did was go into the news in more depth (usually) than what I had already read elsewhere.
They almost always had great pictures to accompany the news stories. I liked both the photographs and the graphics (charts, maps, etc.).
I also liked many of their special issues, such as the ones on health and on women leaders.
I thought their arts coverage was ok, but sometimes, in their feature stories, they were overly enthusiastic about upcoming movies which turned out not to be that great.
If I had the discipline to open the magazine and just look at the pictures, and only read the occasional artilce that I was exceptionally interested in, that would be great. But I'm a compulsive reader, so I would tend to read the magazine from front to back.
I do like Newsweek better than Time, so if I had time (no pun intended) to read a weekly news magazine, Newsweek is the one that I would pick again.
