Microsoft.com Canada posted a Windows Vista price list, according to Neowin. (The list has now vanished, not surprisingly, from the Microsoft site.) In U.S. dollars, Vista Home Premium is listed at $270. Home Premium Upgrade (from a current version of Windows) is $180. But Vista Ultimate is where the prices get interesting. A brand-new copy of Ultimate is listed for $450, and an Ultimate Upgrade at $270. Ed Bott grabbed the full Vista price list before Microsoft pulled it. Guess Microsoft execs weren’t kidding when they talked about their plans to push Premium Vista SKUs (with premium pricetags attached).
