Another feature request, assuming this hasn't already been taken into consideration:
Could we - pretty please with cherries and maple sugar on the top - get some *alternative* means of feeding +5V to the Raspi board, in addition to the recently announced micro USB connector?
This could be in the form of, say, an extra pin on the GPIO connector, or perhaps a pair of reasonably sized (not microscopic) and unpopulated header holes on a 0.1" spacing for directly soldering in a pair of wires to an external PSU.
The issue here is that forcing (most) people to power the Raspi directly from the mains is going to end in grief in many cases. This is due to issues with common mode mains voltage through the internal noise bypassing capacitors used in the PSUs used to power - respectively - the Raspi and any expansion board connected to the GPIO connector.
Many countries less developed than the UK, like most of the rest of the world, does not have standardized and enforced 3 prong mains connectors, mostly relying on just supplying neutral and phase to the appliance. This means no common safety ground. As a result one has to be *very* careful when powering a DIY electronics contraption from more than a single mains supplied power supply. There is a very real risk of having a full mains voltage AC differential between the 'ground' rails of each supply, leading to obvious problems if you just hook things up without due care. This voltage is (hopefully) dulled by the internal safety capacitor capacitance, so the available current should be relatively harmless to a human. It can be easily felt though.
This is the reason why many types of connections intended to go between different mains powered appliances, like wired Ethernet, are rated to an isolation voltage of several KV DC.
With the old connector you could at least warn hardware experimenter about the issue, and tell them to power their whole setup from a single PSU.
To put it differently: Please test that the Raspi SoC enjoys a test feeding 240 VACrms directly to one or more of the GPIO pins through a suitable 10nF safety rated capacitor.
Additionally, while the previous coaxial connector wasn't ideal either, it at least had the advantage of being large enough that a newbie to soldering had a fair chance of successfully soldering a pair of wires directly to the board/connector as an emergency solution, if the proper connector isn't available. I have been working with electronics for more than 30 years by now, and when even I don't have a micro USB connector going spare, I dare say loose ones are not very common. Most people will probably have to sacrifice a factory made cable assembly.
