Microsoft just announced PCs running Windows XP, Windows Vista, or Windows 7 are eligible for a downloadable upgrade to Windows 8 Pro for just $39.99 in 131 global markets and in 37 languages.
Apple announced its next version of OS X, Mountain Lion, would be available as a $20 download in the Mac App store in July. This upgrade is available to Mac users currently running Lion or Snow Leopard, meaning it applies to Macs around three years in age. It's great to note that Windows 8 Pro upgrade applies to Windows PCs around eleven years in age.
The $39.99 upgrade will be available through Windows.com only, and the boxed DVD-based upgrade will be available for $69.99 through January 31, 2013.
Pricing for other versions of Windows 8 still have not been announced.
