Yes, the Leica is, unfortunately, the only digital rangefinder camera that exists at this point in time (I own both an M9 and an X100s. See my photography at <http://simongriffee.com>).
The great advantage of a rangefinder is this: With some practice and experience you can _reliably focus_ the camera _without putting it to your eye or pointing it at the subject_. You can do this because the lens rotation stops at both far and close focus points and you can judge the focus distance by feeling the relative position of the finger tab on the lens, or by looking at the distance markings on the lens.
The other advantage of the Leica is the simplicity of the manual controls necessary for photography: Aperture, shutter speed, focus, shutter release. Unfortunately Leicas are becoming increasingly complex with the addition of video and so on to the M model. Not that I mind new designs, but I think they should also make a more affordable model focussed on simplicity above all, something like [this](http://hypertexthero.com/logbook/2013/09/design-good-camera/).
When I am asked what camera is best to learn photography with I always want to and do recommend a Leica, but I do it with a heart weighed down by the knowledge of the price of the thing.
