A couple of months in I really really want to like it but I don't. I really don't. The concept is very cool, the Indie games for it are really cool and there's some great emulators out there for it BUT... there are too many negatives to make this right.
The controller just isn't up to standards, the thumb-pad touches the sides of the mold so it feels cheap and not well designed. What this also creates is a feeling of unresponsiveness on the thumb-pad button itself as it seems to get stuck in a depressed position quite often. The analog joysticks are actually the best bit of the controllers as they are of a good quality, but they do grind on the top of the controller's surface-plates creating a lot of plastic powder that will no doubt foul up button functionality in the future. The action buttons suffer a similar fate as the thumb-pad button - the holes on the surface of the controller are too narrow with too little margins for the buttons to move freely so they end up actually getting caught underneath the top of the controller. The touch interface area / mousepad is on the controller is actually quite nifty.
But there's more, read below to find out what it is...
