I think that's a pretty large oversimplification.
Microsoft didn't get in trouble just for bundling a browser; they got in trouble for bundling a browser and then using their position of market dominance to lock out competition, e.g., they used Windows licensing agreements to forbade OEMs from preinstalling competing browsers on systems. Microsoft's behavior went well beyond just bundling a browser.
But yes - it takes generations to change a corporate culture, so it may only just starting to change.
There are some things where this is almost certainly the case, like antivirus. For some other things, some of it has to do with selling an OS and not the whole package.
But I do think the cloud is one area where they'd love to have tighter integration -- but will DropBox, Amazon, and Google protest if they do? That's something that Apple doesn't have to worry about at all -- they can tell these other companies to shove it -- we don't have a monopoly.
Update: And we see the next step of their integration with XBox Live built into Windows -- http://www.winrumors.com/microsoft-reveals-xbox-live-will-be...
