mondo84: It doesn't seem like many people are keen on this from what I've read on news story comments and forum discussions.
I can see why people wouldn't be excited, but I don't get at all why people would be angry over it. Valve is still primarily a gaming company. They're just expanding their marketplace.

Stardock also makes productivity applications though.
