Microsoft announced today on their Windows Blog that Windows 8 Pro Upgrade will be sold for a Microsoft all time low price of $40. Microsoft has usually charged $120+ for a Windows Upgrade and the Pro version usually went for an additional $40-$60 so this price is by far the lowest they've ever charged. Unfortunately the deal is only for a limited time - from the time Windows 8 is released (October sometime?) until January 31, 2012.
It's nice to see Microsoft finally getting aggressive with it's products. It's been a busy couple weeks of announcements from Microsoft. First their Windows 8 Tablet/PC, the Surface; second their announcement of Windows's Phone 8; and now this great pricing of the Upcoming Windows. October is going to be a busy and expensive month for me!
