Win 8 moves ~40,000,000 licenses in first month. Upgrades are $39.99.<p>Win 7 moved ~30,000,000 in month one. Upgrades were $120 - 220/upgrade.<p>Vista moved 20,000,000 first month. Upgrades were $129 - 299.<p>MSFT is offering the DVD-version of Windows 8 for ~$30/more per copy so let's just pretend that the fair price for comparison of Windows 8 is $69.99 (since I assume far more physical media went out of Win 7 in 2009).<p>So that's still 1/2 the revenue per upgrade they collected in the previous cycles.<p>Looking at their revenue by division Windows & Win Live have been on the decline:<p><a href="http://www.tannerhelland.com/wp-content/uploads/Microsoft-revenue-by-division-2010-2012.png" rel="nofollow">http://www.tannerhelland.com/wp-content/uploads/Microsoft-re...</a><p>I wonder how drastically this will impact them - if they see a real, sustained gain in traction vs. Windows 7 adoption in the 25% range, that's not going to make up for the shortfall in revenues but certainly would help to lay a foundation for future growth in mobile / server & tools / business / etc.<p>I'm not sure I even have a point, just trying to sort through this data and get a sense of what it means for MSFT macro.
