I can't find the article anywhere, but there was a similar idea done a while back where you would wear a 'dome' that was air-conditioned, keeping your head and shoulders cool. It worked wonderfully for keeping you feeling cool and as a result you didn't sweat.
Also as a result, you didn't notice when your body temperature was rising too high, so it did absolutely nothing to prevent heat stroke or any other forms of heat exhaustion. I'd be concerned about this wristband doing roughly the same thing.
I don't think this is something you should be wearing out for a jog, or while you work out in the fields, or similar.
It sounds great for my situation, though, where I'm sitting around programming in Costa Rica. I could turn off the A/C and let the house be its normal temperature of 85 degrees or so.
They are almost definitely going to use some sort of streaming similar to OnLive. If OnLive can beam playable game streams across the internet and all its attendant issues, then they definitely can manage to stream it across your in-home wireless/wired network.
I feel like this article is close but slightly off the mark. Just noticing from casual observation, it seems like the point can be summed up even more succinctly:
I'm far from being a professional programmer, and until the last year of my life I'd never written anything work-quality. However, you've pretty much nailed it on the tools needed for a beginning programmer: They'll learn anything to do whatever it takes, if it's for a game or something else they're equally passionate about.
That's exactly how I started programming, with QBASIC gorillas, savegame hex editing, and Robot Battle AI programming. I eventually muddled my way through QuakeC, because it was for fun. It was only really at this point that I was ready for proper training materials.
The article does also point out that 'specific' games aren't apt to increase your brain function, which I took to imply that the idea that any one type of game is not the key.
In that regard, it would also be similar to the exercise comparison in that any single exercise is likely to have very limited impact, but a rounded exercise routine provides much stronger benefits.
