Here in Uruguay, they got the OLPC. There is no market, and it works great.
All kids in public school have their own, you see them using them on the streets, public squares. It has its application in classes, and most importantly, it was instrumental in connecting all schools with quality internet service, allowing for remote classes, that kind of thing. It was a success in many regards.

Private schools, on the other hand, are subject to market forces and stuff, but are usually pretty poor in their decision making. For example, my kids goes to a private kinder, and their usage of computers is pretty dumb, they still have a computer lab kind of thing, mainly because they weren't wise enough to get a complete solution. Public spending was a lot better around here.

I was just answering _your_ alternative proposal.
I did look at the story, and I think it's a cool idea, that might even end up having some kind of application. This is research, not engineering.

Power over ethernet implies cables.
Expected capture rate is not always 30/60fps.

Just think about it.
This is not an economic problem. It's a problem with regulation, strategy, or whatever.
Wherever you live, you have roads to get there. Roads are thousands of times more expensive than fiber, and they need constant maintenance, investment, and rebuilding. You also have electricity virtually everywhere, or you wouldn't care so much about internet access. Internet access is chump change compared to the rest of infrastructure that you keep building and maintaining.

The problem must be somewhere else, not in the level of difficulty, or the cost. Maybe the strategy, the regulation isn't working, but it's not because it's hard.

Alright

First thing first grab a thick Windows Server 2008 or 2012 book from Microsoft Inside OUT and walk over to your system administrator and wack him on the back side of the head with it!

Then proceed to open the chapter on creating Group Policy Objects? disable java in internet zone under internet options in the control panel. Then create another one to enable java scripting in the intranet zone and add Pearson's to this. DONE.

It is negligence to run this on the web and any system administrator worth his salt under has it enabled for trusted zone sites or intranet sites. Safe, secure, and works with old crud.

IE has it's advantages at work over Chrome. One of them is managing ancient insecure crud and this is where is it useful over Chrome.

There is always IE. You know just saying for those who don't and do not care about new things

... take what I said about HTML 5 and CSS 3.

Try getting a site to look right in IE 6? The workarounds which interact with other workarounds with fixes that break other fixes.

Apparently you haven't read the W3C on HTML5 and CSS 3 specs :-)

It is 2015 and time to move on.

The only java I still see are IE specific or I shall say IE 5.5 1999 era specific intranet sites in quirks mode running under ancient IE emulation in IE 8 or earlier. Funny how Java was decided upon because of portability and then they use IE specific bugs and css to get to not run in anything else. :-)

It is dangerous and wreckless to have it enabled. Infact Oracle should be held liable as it is negligence to use the web plugin.

Because ObamaNET is doing a take over by the communist!

Government control, government that wasted 19 trillion, government censorship, government, government, oh and Obama deciding everything and ENOUGH!! Fellow Tea partiers and Republicans we must unite at all costs to protect freedom! Go read the drudge report comments or comments on facebook?

This my friend is scary propaganda that if you are conservative leading will poop your pants and want to end. Sadly these comments I wrote above are actually believed by followers of Hannity, Fox news, Rush Limbaugh and others.

Linux has been obsolete since introducing assembly code. Minux touches the hardware in just 100 lines of code and macosx is a micro kernel as well.

It is 2015 and not 1985

ipads are most useful if you want to consume content. Not much to experiment with them, at least not with the Ipad itself.

3D printers are tools, awesome tools. They have nothing in common with Ipads, you can do stuff with 3D printers. Think of them as the logo turtles of today. They show kids a tangible application of programming, physics, math.

Teachers have the opportunity to choose to use that for teaching, or just let them tinker with cool stuff.
  And I mean single teachers, they can just print a mechanical assembly, or an atom model, or a dna model, a geometric shape . With already existing, easy access easy to use, and most importantly, easy to share tools.

Compare that to the authoring you can do with an ipad (or a classroom full of ipads) by itself. You _might_ be able to sketch something, but the tools are just not there, or available.

My point of me being a jackass is the dumb politicians and voters and corrupted influences who will say it is a government takeover and a RINO move as a tax increase when you want to charge more for a scarce resource.

This is what needs to happen but it won't as the agriculture community has too much power and will run fancy ads agaisn't you in the elections as a socialist if you dare charge them more for water.

You would need to repeal the water give away. That won't happen. So the other step is actually creating a tax to limit consumption which will brand you as a socialist until all the water runs out and we have a crises where everyone including the agricultural industry all lose. We are heading towards that right now. 2/3's of the state senate is needing for this and no politician on the right will dare do this to avoid not being re-elected.

Funny the French are cowards for not supporting the Iraq war. How unpatriotic and muslim loving ...

But today seems like the French had a brain while the Americans were flying their flag singing patriotism under the scope of insane nationalism and didn't even realize they were manipulated.
