Kotaku: It used to matter whether a portable video game machine could fit in your pocket. The Game Boy was a brick, but you could jam it in your jacket pocket. The Atari Lynx was a small log, but ridiculous ads on TV showed it too could fit in a coat—probably as well as a smuggled carton of milk, if they were being honest.
We had the Game Boy Pocket, the Game Boy Micro and the ever-slimmer line of PlayStation Portables. The DSes were mostly pocket-compatible, until the Nintendo DSi XL emerged to threaten any tailor's best seams.
Today I believe we're past the pocket question. There are more dire matters of fit over which to worry. The PlayStation Vita, the most impressive handheld gaming machine I've ever touched, may squeeze into my coat, but I'm not sure it fits into my life.
