I've read a fair bit about it. Apparently in the first years, the current generation Prius's traction control software was very aggressive in preventing wheelspin, which combined with the lousy OEM tires (Goodyear Integrity, widely detested) created problems on very slippery surfaces. The computer would cut power too quickly at the first sign of wheelspin. With good tires there wasn't a problem.
Then the software appears to have been changed and reports of the problem pretty much stopped. I don't know if dealers reprogrammed the software on older Priuses, or if those cars have naturally gotten new and better tires. But my 07 has always been a champ in snow/ice, with snow tires admittedly.
I read the Prius forums and by now the complaints about snow/ice performance are the normal ones you'd expect from people who took their Prius with the OEM tires into 8" snow and wonder why the car didn't go as well as on dry road - dummies, basically. I don't see the software-related complaints now.
