dforristall alerts us to an odd move by Microsoft: cutting the price of retail boxes of Vista in many markets. Analysts didn't see this one coming, and they are scratching their heads a bit over it; one called it "very unheard of." The price cuts vary by country — they're largest in the developing world where piracy levels are high — and they don't apply to OEM copies of Vista, which account for 90% of sales. "Gartner analyst Michael Silver said the move... is puzzling... [He] noted that the market for such upgrades is fairly limited. Those who bought XP in the fourth quarter of 2006 got a coupon for a free Vista upgrade, while most of those who have bought systems since then have gotten Vista. Machines purchased prior to 2006 probably aren't all that attractive as candidates for a Vista upgrade... 'The whole notion of upgrading PCs has sort of fallen by the wayside.'"
