Haha, my camera is 3.2 Megapixels Not.Yeah, but this camera would probably be very useful for large-format photographers. And like the other person said "Amateur aerial shots" is quite right, that would be splendidly useful for that. Though, I doubt many people will buy it, it probably being in the high hundreds to low thousands price range. I'm not quite sure what large format photographers use today. But they are probably in the know-abouts of this already anyway.
You should purchase a wireless router. I'd go with Linksys (division of Cogeco), Wireless G.As for the computers, really any computer will do. If you want to go the route of laptops, get one with a build in wireless chip.Hopefully your building isn't fully steel. Haha!
