Leia uses a Leica T with beautiful results from her travels around the world. It is a mirrorless camera, uses interchangeable lenses, and I'm very happy that it has attracted a younger generation of Leica photographers.
On this forum- we have a small group of active posters that tend to be more interested in the Rangefinder Leicas that can use a variety of lenses going back to the 1930s. The Digital Leica Rangefinder is as close to operating a classic manual focus film camera that you will find. Personally speaking, I have less interest in keeping up with the latest in digital camera bodies coming out than there is in restoring a lens from the 1940s.
With that stated: I keep up with Leicarumours.com and other sites, they do a fine job of reporting what is new and some of the "early adopter" problems.
