DarkTable update

For those of you not aware DarkTable is a F/LOSS take on LightRoom. For Linux OS only.

I noted in another thread that the new 0.9 version is out, with an increase in speed through making use of the GPU on your graphics card. Even on my old nVidia GeForce8500GT. Plus many new features as usual.

But in addition there's now a revised 55-page manual.

I wonder how this compares to lightroom in practice. Running a linux OS like Ubuntu is a nice idea for general use but i've always kept running Windows to use PS and LR3.
