Sixaxis is the worst name for a controller in the history of the world, whether you spell it entirely in capital letters or no. Luckily, the Sixaxis also appears to be the worst controller in the world, so it's aptly named!
From an IGN hands-on of the Playstation 3:
"Compared to Microsoft's uber-comfortable Xbox 360 pad, the SIXAXIS feels cheap, plasticky, uncomfortable and disconcertingly light - almost as if it's going to fly out of your hands during those more extreme gaming moments. More worrying still, the newly-designed lower L and R shoulder triggers feel more like they belong on an early controller prototype than the near-final model. Replicating the 360 pad, rather than being simple shoulder-mounted buttons, the triggers are now hinged horizontally along the controller, with pressure forcing them inward along the bottom - like triggers then, really. Trouble is, they're placed almost unnaturally low meaning we found ourselves operating them by jamming our fingers in between the hinges to apply pressure, rather than using the buttons themselves. What's more, the triggers are convex, with no grooves to keep your fingers in place - an issue further compounded by their smooth finish, offering no resistance against your finger tips. Invariably we found our digits slipping off with the triggers snapping back to their default position. Bah."SIXAXIS? More like SUXASSES, am I right? Wokka wokka! You guys can steal that joke if you want, I haven't copyrighted it or anything. Maybe we can get a meme going.
Wow... that's not good news.
