It's interesting that the user experience varies a lot with this power hack.
Some notice hardly any difference and even with the latest firmware people experience reboots.
Ironically, reboots cost a lot of power... so when you have a few (or even one) a day does it really make a big difference in power savings?

Perhaps the Autodisconnect app is a better solution to try first.
I don't like reboots.
But... as some don't have any reboots at all, do you also belong to that group of users?
Because there are only a few that AND really notice significant worthy improvement AND do not suffer from (frequent) sudden reboots.
