What the pi should do is monitor the voltage level of port it is drawing from, if it draws it down, it should turn on a fault LED or disable onboard services (like ethernet and usb).
to a "normal" round plug.
The whole point is that most people (especially the target market) have a spare USB charger hanging around. The Pi takes exactly the same connector as your mobile phone it one less bit of kit to buy.
It will work fine in 95% of the cases, but 5% will ruin their computer USB port, because the PI is not within the specs. You can supply juice to the 5V and GND pins on the GPIO header. That probably a better power inlet interface than either a ramshackle micro USB connection or a janky barrel plug.

What the same: Same Broadcom BCM2835 Chipset Same 512MB RAM Same full size HDMI port Same 10 Ethernet port Same CSI camera port and DSI display ports Same micro USB power supply connectionWhat has changed: Now comes with 4 USB ports so you can now connect more devices Nike Flyknit Racer Hyper Punch than ever to your Raspberry Pi. There is a 40pin extended GPIO so you can build even bigger and better projects than ever before. The first 26 pins are identical to the Model B to provide 100% backward compatibility for your projects. Micro SD slot instead of the full size SD slot for storing information and loading your operating systems. Advanced power management: You can now provide up to 1.2 AMP to the 4 USB ports enabling you to connect more power hungry USB devices without needing an external USB hub. And many people have spare 1A+ chargers lying around as mobile devices tend to break before their chargers (ramshackly plug notwithstanding). It also lets you draw from the fairly rich ecosystem of other USB power gadgets such as external batteries. I be really annoyed Nike Flyknit Roshe Two

The Ethernet chip is a new one tho maybe it a little less terrible?(No idea Nike Flyknit Racer On Foot
reread the usb spec. I have several old Belkin hubs that will terminate (with prejudice) power to any port that draws over 550 mA, until you physically power cycle the hub. This is annoying for obvious reasons, especially on 7 port hubs with beefy power supplies, so most hub manufacturers don do that anymore.

my applications for the rpi don depend on it being a speed demon on the network.)
