I spent several hours playing a half-dozen Playstation 3 games yesterday always, of course, using the Sixaxis controller.
While the controller does feel lighter than I'm used to, I didn't notice any significant issues with it at all in playing the games.
The only weird moment came when I was playing through a chunk of Resistance: Fall of Man. It's strange, after feeling the rumble and shake of gunfire for so long, to suddenly play a shooter that doesn't include it. It almost felt like playing without sound. While it was unnerving for a few seconds, I quickly got used to it and then promptly forgot about the lack of rumble all together.
While the controller is as light as a feather, it still feels pretty solid in your hands and the thumbsticks were absolutely fine. The R2 and L2 triggers jut out a bit more than with the PS2 controller and the trigger pull on them is much more significant. All of the games I played didn't seem to make use of that in anyway.
I wouldn't be surprised if down the line games starting make the R2 and L2 buttons the default triggers for shooting, simply because they feel a bit more like a trigger.
The motion sensing for games remains tight and surprisingly intuitive. I played through the demo of Lair and was happy to see that the motions were very natural and mostly easy to perform (even with a broken hand).
While gamers are likely going to be initially taken aback at the light weight of the controller and the lack of rumble, I suspect it's really not going to become an issue. Your hand gets used to it so quickly that it doesn't seem that problematic.
