I plan on purchasing one of these routers. But will it be possible for it to use timemachine with it using a usb attached ext HD to it or no? Also how does the airdisk work? well? I am interested in it because of the 3 lan gigabit ethernet ports. Was planning to wire my ps3, xbox360 and powermac g5 desktop to it. Since i xfer a lot of files back n forth and stream media. My old round airport 802.11g is getting old too.
