Sure, there are some downsides to this, and not everybody wants cloud gaming - on the other hand, there are a lot of benefits. For example, you don't need to upgrade your graphics card every few years to play the latest games with the best quality settings. Consoles could keep up with state-of-the-art graphics, and PC games that arrive late in the console cycle won't be dumbed down so that they look the same between the PC and consoles. Going to a LAN party? Leave your desktop at home; bring a small portable device (say a phone, tablet, or ultrabook), a controller, and maybe a display - or just plug a controller straight into a TV, for that matter. Find an awesome new game? Tell your friends, and in under two minutes, they're playing it with you. No need to download it, or go to the store to buy it. Like Mac OS X, but you're a gamer? No need to have two computers (one for gaming, one for other use), or reboot into Boot Camp. Or more generally, no need to worry about whether the awesome new game is available on iOS, Android, Mac, Linux, Windows, Playstation, Xbox, Wii, etc. - use it on whichever one you prefer. And use it on different platforms at different times, without having to buy it again.

There will always be a market for buying physical copies of games so that you own them; you can still rent and buy DVDs in person, despite Netflix's best efforts (and huge success) with DVDs-by-mail and streaming video. But it does have the potential to disrupt the market, and introduce some new concepts and business models that just aren't possible otherwise.

OK, I was playing fast and loose with my English. I should have said that "there is a positive correlation between voltage and power and energy" or something to similar effect. As opposed to no correlation (or a negative one).

In any case, at least for a lot of signaling types, P=V^2/R doesn't matter, because R is approximately infinity. What matters more is charging and discharging the capacitance of the traces on the PCB, etc., so E=1/2*C*V^2 is the quantity of interest. With memory, this can vary, as there may be termination (e.g. a resistor to ground or some reference voltage), but that depends on the type of memory as well as the specific implementation.

Volts are not a measure of power. Watts are.

More importantly, energy to accomplish a particular task is what really matters. Though usually, we're just given average or typical power numbers. But your mobile device's battery stores energy, not power or potential.

At least the voltage is proportional to power and energy...

...says the article.

I should say not, given that the photo of the plug at the top of the article would obviously never fit into the photo of the socket halfway down. The accompanying plug photo in the second photo may not have the same problem (at least the two parts of the plugs don't protrude different amounts). Anyway, graphic designer fail.

And, for a less-superficial observation, who's going to want to open two port covers on opposite corners of the socket, especially given that both are likely to be spring-loaded? You're gonna need three hands to plug the car in! Let's hope those were subject to the artist's wild imagination as well.

I've seen similar figures, and yes, they include the battery (which isn't necessarily Li-Ion; hybrids tend to use NiMH because of the lower cost, while electrics need to use Li-Ion for the the better energy storage per pound, in order to keep the vehicle at a reasonable weight).

But more importantly, I cannot lose if I do not play.

Probably written by somebody that missed the same article when it was first written. I remember reading this in the newspaper long before I could drive, probably early 1990s when airbags were just becoming popular. I was able to find online articles dating back to 1996 on this topic.

I tried the 10 and 2 positioning once, but I couldn't get my knees that high.

Sigh. I thought that joke should have been obvious. Hell, if you think anything in that whole sentence was serious...

The joke is that, being an American, I think it surely must come from the US, because, since we invented beer, and we created Guinness (read up a few levels), we probably invented Irish whiskey too. I'm just happy that other countries picked up on the whole beer thing and have started their own great microbrews that the locals love, like Foster's and Heineken.
