Well, the 'problem' with 3G activation is that it's not instant (Probably from 5 to 15 seconds, depending on operator, signal ccondition, etc). So, the earlier the trigger can happen before you're 'ready' to use it, the better I know voice activation can be really geeky, awkward and unnatural, but it's one of the conceptually 'neat' way to trigger the device without having to handle the device and wait it out in front of you. PS: Yes, you can just say "Heck, it's only a 15 second wait." and shower this discussion with morality/behaviorist judgements I'll just preempt that with a figurative sidestep as we're trying to find better ways to enhance Maemo and the N900 compared to other platforms.
