I've been using PDAs since the old Palm Professional and I really appreciate
the way they handle the power button.  No state is lost, it's virtually
instantaneous (much like waking the 770!), and I can grab the device, jot
down a note/etc., and switch it off very quickly.  It's rather confusing to
hit the power button on 770 and be presented with a menu; I want it to
switch off (or appear to), not ask for more input.  I'd also like it to
ignore screen taps once it's pretending to be off-- unless it sleeps
automatically.  This way it doesn't wake up inadvertently in my pocket, but
it's easy to tap it to wake it up again if I let it sleep while doing
something else.
  Playing music should keep going as it does currently, although an
on-screen button to make it switch the screen off immediately would be
great.  I really don't like having it glowing in my pocket, and having to
place the cover on is awkward enough (not a one-hand operation) that the
power button is really important.
  Behaving like a Palm will make sense to all the former users like myself,
and delight Zaurus users (myself included) who hated having to hold down the
power button to make it do anything as well as the considerable lag before
it was responsive again.  I would reserve a long press of the power button
for either a "hard" power down if things lock up, or to present the menu at
that point.

Just my 2c,
Larry
