it would be great to purchase directly from Netgear power supplies for routers like they are doing at Dell,
I like the Apple way doing their router too they include the power supply in the Airport device just a ac power cord to plug in and I'am sure that there is room in the router to shield a power supply in side the router fron rest of the electronics.
The block power supply is very old idea and cheaper to use it has place like cell phone chargers and even that is giving to wireless charging were you sit your phone a charging station and a coil in the phone puts up the rf signal from the station and converts in dc voltage to charge the battery.
