I finally bought myself a 17-70 and I think its superb. If you can forgo the f2.8 I think its totally the way to go. It has some caveats, but nothing really deal breaking for me. Its also far sharper wide open (f4 of course) compared to the 16-50. The extra 20mm or reach is extremely handy for head shots and landscapes are usable at 70mm too.
