I wish they'd make something like the processors in handhelds but using more normal architecture. In other words, a processor in the range of 100 to 400mhz, that's frickin' small, doesn't take a bit of power to run, and is fine with passive cooling, if that. It would be easily possible with current technology - for instance the old laptop I spoke of earlier (~75mhz) overheats itself very quickly if it's put on an insulating surface such as a bed where the 'feet' can't raise it up, yet my handheld (even when overclocked to 462mhz) which, like the laptop, has no fan, remains cold metal throughout. The only bit that heats up is the backlight if it's on full brightness.
Now if someone made something like that to stick in a laptop, it'd be perfect. 400mhz is enough for anything other than those newfangled three-dimensional games rampaging the market these days. And, to be honest, it isn't much of a loss. Most games around at the moment are the same, give or take a bit of graphics. 2D games get the most innovation, since you can't just overload it with pretty graphics and call it a sequel. Unless you're Sid Meier.
Unfortunately, it's all numbers these days, so it won't happen. Fun ol' world, innit?
