Early peek at Vista pricing shows big spread

From Arstechnica:

We know about Vista's many editions, but the pricing has been something of a mystery. Over the weekend, Microsoft Canada accidentally leaked details about Vista's Canadian pricing. Now Amazon has published a list of the US prices for the various Vista editions, along with a release date of January 30, 2007.

Here's the skinny on the pricing from Amazon. Keep in mind that pricing and release date are subject to change; in fact, a Microsoft spokesperson told Ars that the pricing is not set in stone.
