Currently, developers use the in-application ads to monetize free applications. This means that the only people who will see those apps are freeloaders who don't want to pay $0.99 for the full version of the app. Those folks won't tap on the ads, and even if they do, they won't buy stuff. Epic fail.

Older devices will have a trimmed down version of the iPhone OS 4.0 which will not include multitasking because the older devices have 128MB of RAM.

They will most probably have the ads API.

Chrome might, yes. but Firefox would probably not be able to implement this as quickly as MS since creating a cross platform implementation for this will likely be problematic. Remember, MS only has to support windows !

Amateur has a number of meanings. The relevant one is:
a person who engages in a study, sport, or other activity for pleasure rather than for financial benefit or professional reasons. Compare professional.

In other words, with some extremely limited and very specific exceptions, hams cannot be compensated for their work.

Define "most". It may be true in some areas but I have a hard time believing it's most. While in many areas you are encouraged to have taken (free) NWS training to become a Skywarn spotter, you aren't required to do so. As an example, the New York City metro area most certainly doesn't require RACES certification to participate in any of the nets, and as a former Skywarn Deputy Coordinator, I can tell you that such a thing was never even discussed.

That said, it is unfortunate that there are some people who seem to have a "control complex" and are more interested in being in control of others than they are of providing service to others.

Needless to say, 100w is also about the same power as a 100 watt lightbulb, to make an even simpler comparison.

Although more challenging, you can also communicate around the world with far less power (what us hams refer to as "QRP", meaning low power). Many people enjoy the challenge required to "work the world" with 5 watts or less, sometimes much less. While you can do this with a GSM cellphone with 2 watts of transmit power, it requires an awful lot of infrastructure to make it work, and the aggregate power required by all that infrastructure is substantially higher.

You won't find ham gear or information in your local hobby shop (or at the anachronistically-named Radio Shack, which doesn't sell much in the way of 2-way gear other than cell phones.) However, you can find a lot of information about ham radio at We Do That Radio or the The American Radio Relay League as well as a Google search, Wikipedia, etc.

In addition to the tutorials available on the site, there are a number of interviews with the scientists where they explain specifically they wants humans to look at the images. In fact, they want multiple people to look at each set of images to try to get a more objective opinion.
