"I just moved into a new apartment and have been reading about all of the new power strips out there, especially the green ones. I was wondering if you had any suggestions about which "green "power strips are out there with decent joules ratings. And when I say green, I mean power strips that have the remotes or switches to turn off all electricity flowing to certain plugs and with at least 2 plugs that are always on. I was looking specifically at sub $50 because I will need two, but if that is not possible I could be convinced otherwise. Thanks!"
The Wifi on the 604 hasn't been crippled like it has on the Zune (you can wirelessly sync, browse and manage remote directories, browse the net, play media directly off your network and even run the 604 as a self-contained wireless NAS).
However as far as I know, the OS hasn't yet been opened up for anyone to play with.
