Exactly my thoughts. There are a couple of things we have to be
mindful of as we step into the wild 3D world...

 - memory footprint -- those smooth transitions count on having
various full-screen buffers, one for each screen you might want to
slide smoothly into.

 - batery burn -- the OpenGL API was originally designed for high end
workstations, and has some battery-depleting features such as a hi-res
timer event that triggers all the time and prevents sleep

The iPhone uses these smooth UI tricks (to a fantastic effect), and
its battery life is a fraction of every other phone -- I'd say that
the 3D niceness is part of the reason why.

cheers,
