Sadly I've turned away from Ggplot to Lattice in a major way simply due to the speed. If you're plotting a significant amount of data then ggplot can easily take 5 or 6 seconds to plot a panel compared to the nigh instantaneous Lattice library. Which I'm fine with really. Hadley Wickham is doing interesting stuff with ggplot that shouldn't be burdened by racing Lattice. It does mean I'm less likely to use it for exploratory data analysis though.
