can iostat _really_ behave like top ?

How about something like:

iostat -h -w 1 | sed -e "/tty/s/^/$(echotc cl)/"

to insert a clearscreen whenever the header is printed (i.e. the device
ordering changes or 20 lines are printed)

Then again, what do you have against scrolling?  With your original
command, not only do you see the last screenful of stats even when
devices change order, but you can scroll back and see farther back if
you want to.
