There's an eject button to let you grab the phone, and the phone exits standby as soon as it disconnects from the charger - I don't get what problem you are trying to solve?
From the OP's repy in another thread it appears that ejecting of the phone was not initially shown/written about in the first iteration of the blog post. Maybe the parent comment only saw the post before the update.
2) An independent time display also would be a tiny load, so the trickle vampire energy isn't being wasted.
3)Removing the only moving part also simplifies using the phone immediately. Do you want to be fumbling with an eject spring latch when someone is having a heart attack?
4)Compatibility: Now it works for Android, iPhone, Blackberry, or whatever other devices already use wireless charging.
