All solid state electronics ... very low power requirements.

There will be probably millions of these thing lying around for a long, long time if humanity suddenly goes poof. Many of them will be siting in protected, stable environments ... all that will have to happen is for one to get exposed to light and the little 0 will show up on the screen, ready to take input.

Even if we found out we had an unlimited supply of carbon-based fuels, if you factor in all of the associated costs with burning them (production, transportation, environmental, health) ... it turns out they're not really that cheap.

Unfortunately, we don't factor in ALL fo the costs into the price of our 'cheap' fuel sources ... we're incurring a huge debt because of it, and the books are going to balance sooner or later. The environment will get its pound of flesh.

Obama's only been in office since Jan. 20th ... in this time his primary focus has had to be the economic crisis and the wars in the Mid-East.

Bush had a full 8 years to put all of his policies into effect. Do you think it's reasonable that Obama could reverse all of that in such a short time in office? Our new President has been very efficient since taking office and has put many wheels in motion trying to reverse much of the damage that Bush Co. has done to our country. But he can't do it all with a simple stroke of the pen, and he doesn't have the Constitutional authority to just "make it so" with a stroke of his pen for many of the things he'd like to do. His policies must follow the process of law, or he's no better than Bush.

Any objective observer would give Obama very high marks for his first 74 days (as of this writing). Granted he's got many people on the right who will cry foul at many of his moves, and people from the left who are whining that he hasn't given attention to their pet issues, but you have to admit the man has been very busy and very efficient even if you can't agree with what he's done.
It will take time for the 'cultural change' within the government to take hold. Many Bush appointees still hold office, many gov't agencies still have the mindset of the last 8 years and it takes time to enact cultural change within an organization as complex as the US Government.

It's not the time to judge Obama yet, give him time to get his agenda in place. Stay vigilant, yes. Complain that everything hasn't changed yet? C'mon ... be realistic.
