Apple Store 5-star reviews feature garners 1-star reviews

Yep, agreed.
Lame. I can see a company not wanting to open the can of worms that is developing and hosting a system that could result in the display of negative feedback at their expense. But really, did they think they would escape opening the other can of worms, which is the backlash against their obvious lack of transparency by disallowing feedback?

Sure, there would be some disparaging ratings of Apple products. Maybe even a couple of Wintel zealots with a lot of spare time and no social lives would skew the system. But it is highly likely that the majority of ratings for Apple products would be positive, given the trademark enthusiasm of Mac fans, who presumably make up the lion's share of the traffic to the Apple Store web site.
