Update

Well, still using the KDE version - which speaks for itself.

After downloading the iso and installing it, I still ended up getting another huge load of updates - which was a bit of a pain with my lousy interwebby speeds.

So far though, I haven't found any real issues. Wireless just works (which is much better than the Ubuntu version, which lost the connection regularly!) although I prefer wired.
The other problems which plagued the Gnome version of PCLOS don't seem to be present in the KDE one - presume this is because it is much more mature.

I think I shall install this to my main PC as well. It currently runs Ubuntu 10.04, but is rarely used anyway because it is upstairs and it gets cold in the daytime up there.
