I actually switched from Kubuntu to Ubuntu just for the sake of change. Only thing I miss is split view in Nautilus, although it seems there are patches available.
You'll be pleased to find that Nautilus in 10.10 has a split pane view. Just hit View > Extra Pane (or F3). :-)
10.04 here... split panes work great.
Actually installed Xubuntu on a netbook (old hp 2133).
