Got some things to moan about.
Microsoft still think its ok to interrupt a gaming session to force a firmware update, I can understand them doing it after you shut the game down, but i dont think they should ever be just booting people out of games with no warning, boom the screen just appears.
I checked the firmware information, and they released it only 10 hours before the mandatory update time, thats a ridiculously small window.
Also the energy saver mode, I first noticed this problem when my IHD started working, I then plugged the xbox into my UPS for rapid reading updates, and in energy saving mode it basically rapidly moves between 1w and 30w every second, the IHD reports a constant 20w (so I assume the average for the polling period), I believe this is considerably higher than what UK regulators expect for standby devices. So I do unplug it now when shutting down.
