What if I just want to select a few words or a sequence of text that 
spans several lines & sentences?  I would like to suggest a double-tap & 
drag (tap, tap-hold, & drag) to select an arbitrary amount of text.

I agree 1 second is around the perfect duration.

Scrolling vs Drag & Drop could be context based.  If you press on an 
icon and drag it drags & drops, but if your initial press is not 
directly over an icon it scrolls.
