On: Windows 8 Pro Upgrade to cost $39.99

[r00fus]

Apple has consistently stated that they don't make much money from their App Store (or iTunes content in general).

How are Microsoft (and Amazon, whose entire $199 Kindle Fire pricing) going to make money in this market?

No doubt they want folks on the store, but I question whether this is the reason behind the $40 upgrade pricing.

I would wager MS wants to foster a stronger Windows App ecosystem and not necessarily App Store profits.
