Comment(by sascha_silbe):

 While this could be quite convenient, we should give the user the option
 not to do it. Imagine someone startin either a lot of activities or a
 single buggy activity that hogged the computer so much that shutdown was
 the only viable option. We certainly wouldn't want to turn that into a
 vicious circle by resuming all activities automatically...

 Thinking more about it, adding suspend-to-disk
 ([http://en.wikipedia.org/wiki/Advanced_Configuration_and_Power_Interface#Global_states
 ACPI S4] / hibernation) support to Sugar might be a better idea. It has
 the same power draw as powering off (ACPI S5) and we don't need to do
 anything fancy like auto-resuming activities. Startup time (reading RAM
 contents and device state from disk) usually is also much less than full
 boot - especially with Sugar.
