What? Oh, no no no. They don't literally explode. But they've gotten much more expansive, and sometimes smaller. Now they can hold something something like 30 thousand songs. laptop batteries can now last 8 hours, still providing top notch graphics. Wifi is everywhere. Fiber optics are really expanded.
I think a lot of the technology is more about making things better?
but if you're thinking like.. gadgety goodness? there's so much to choose from. I'd start with the iPhone. offers the most chance to play.
