No in PalmOS off is not off. On Tungsten T2 you can set it to be waked
up by initiating bluetooth connection with it when it is 'off'. You can
also schedule alarm procedure which gets executed and the display is
even not waked up if you wish. Unlike with N770 you really can't
shutdown PalmOS and battery is not removable in most units so there is
not this type of problem there. Solution for N770 would be to remove the
poweroff item to make it behave like PalmOS and maybe also implement
suspend in kernel which pauses all tasks and powers off unneeded
hardware. But the current system is also good, just don't let users
shutdown the device so easily.
Why?!?
Why not let users shutdown easily? Because you keep the state and don't
need to boot the device through tons of /etc/rcx.D/* (and do it in
advance without user noticing anything) to handle single alarm and then
shutdown it again. Because with proper suspend (or should it be called
standby?) instead of poweroff you may save enough battery to have it
look like real poweroff without any ill effects. Because this is a PDA
or 'Internet Tablet' not unix server that can take minutes to boot or
shutdown and noone cares because you do it once per several years.
Current 'Switch off!' mode should be something people should do only
when the want to put the device to drawer for months and want the
battery charged (which you could do by removing battery anyway). On ipaq
you have very awkward key combo for this mode buried deep in manual on
page noone reads. Not directly in menu on device. And yes in this mode
alarms are not supposed to wake up the device :-)
Power management efficient enough to make suspend meaningless
If the suspend is taken as replacement of poweroff the reason is here
because it should pause the device in the midle of playing video or
sound. Take it as the current 'Lock touchscreen and keys' plus pausing
sound and network plus anything that takes power or keeps state that is
useless after couple of minutes.
Maybe suspending tasks is not needed after all just send them different
signal so they know device will be paused for many minutes and may wake
up in different environment so they should really finish/stop what they
do. So it is probably about more device modes than current offline or
flight mode (are they same?) and normal.
I cannot really understand why a lot of people here seem to want
crippled functionality just because other platforms have limitations.
Instant poweron and proper pausing of everything when you press one
button is not crippled functionality but very simple and neat thing Palm
devices do and people expect.
