The real drive behind this might be the need for power in the military (though that does not make a lot of sense as the power will be off during the night, and the batteries the military would need to store power for use overnight would likely be bigger than the oil fueled generators they replace). It might be the military sees this as a way to get a new weapon in the sky, consider their recent work with the "pain ray", a microwave gun that causes intense pain by stimulating the nerves of the skin, perhaps such satellites (which use microwaves to relay their collected power to the ground) could do double duty and be used to cover large areas of a battlefield with pain rays, thus, knocking enemy troops out of action prior to an attack. 
The Panasonic Lumix G1 (also here on PhotographyBLOG) will be the first of the micro 4/3rds cameras, it will have a flip out 3 inch display (it looks like it is fully articulated and can be turned face in to protect it, yeay! this was a feature I really loved on my Canon G1) with a 460K pixel resolution (which still might not be enough for manual focusing). It has a very high 1.44 million pixel resolution viewfinder (so that might be enough to do manual focusing on, but I found that the 900K pixel view finder on the Minolta A2 was not enough for this so I am expecting this will will not be enough, however Panasonic is using a different technology which effectively stacks the RGB pixels so it might be a much sharper display than the traditional pixel count implies.). It got HDMI output too, so you can inflict painful hours of slide shows on your friends and relatives. Digital Photography Review has a preview of it here.
