The greater bounce from the steeper trajectory is as significant in tennis as it is in cricket.. but my point about the "bite" (and variability of "bite") is that the revolutions on the ball should cause the ball to "spit" off the pitch (possibly not so much as to be noticed by the average pundit watching TV, and certainly not enough to be spotted on the ground... but enough to introduce a fairly random element to the pace and tracejtory after pitching).

In tennis this "spitting" off a good length is highly visible when the male clay court specialists (and strangly enough Tim Henman) are serving (especially right handers trying to drag players wide from the advantage court and vice versa): the dip is quite noticable (the ball dropping on the tramline a good 3'-4' short of the corner) but the "spit" then kicks the ball slightly further out but (most noticably) faster and flatter than a "normal" bounce.

As with cricket the trick is to either get so close to the pitch of the ball that the variability in trajectory is less pronounced.. or so far back (often 15' or more) that you've time to adjust appropriately.

I guess it's variability of bounce (and pace of the deck) rather the scale of the bounce that counts: consistent high bounce (as Giles gets on fast bouncy wickets) should really be quite playable for strokeplayers with a good eye (something commentators always seems to fear on such pitches). You may be right, of course, in suggesting that uneven bounce off a dodgy track is the only reason he seems more successful on "turning" wickets... but if the tennis anaolgy is right then I'd suggest the revolutions on the ball are actually caopable of generating uneven bounce even on a very "true" spinners-track.
