There are still a few packages that use pstricks and won't work with pdflatex; I use one of those (pst-barcode) to print qrcodes on labels and I have to go throught dvi->ps.
You can still get pdf by adding ps2pdf to the toolchain, of course; I just don't bother with it because my printer is perfectly happy to accept the resulting postscript, but I know I'm in a minority in that.
