I personally use kdenlive right now and it suits my simple needs very well. Actually,
for the first time on Linux I am quite happy with basic video editing.
As for Ralf's prediction of everyone jumping on Linux, I think this is not happening in
the near future - if ever. The percentage of desktop Linux usage is very-very low, even to
this day. The highest number I ever heard was 10% and it was the only time I heard it. The
rest of the numbers are always within 5%. And while none of these polls are accurate,
I do see that Linux Desktop, in spite of its wonderful progress, is nowhere even near mass
adoption.
In fact, even if we magically get all the software everyone needs right now, the adoption would
be slow.
