I agree that that monopolistic era was especially pernicious. It wasn't just that Microsoft controlled a huge share of the desktop market; it was that this made them a de facto gatekeeper with regard to technology before the Web. Also, there were a lot of startups that couldn't get fair acquisition prices because there was only one buyer. The only good thing that comes out of monopolies is R&D (e.g. Bell Labs)... but I'd rather see R&D propelled by employee demands for autonomy (when there's lots of competition for talent) than by executive largess within a monopoly. One of the most exciting things to come out of Microsoft's research department is F#, and that emerged after the monopoly era was over.
Apple and Google both make excellent products, with completely different approaches but an end result that's great for users. Competition is good for products and also good for employees within companies (competition for talent).
On the contrary Google is distributing an Open Source OS with well documented APIs (that RIM is using to run Android apps as-is), they aren't requiring any anti-competitive agreements/royalties from anyone to forbid them using alternative OS etc. They are betting on good-will and competence as far as I can see - that manufacturers can use it on its merits rather than being forced to do it. Of course in the process they are making money but it's win-win for everyone.
IE killed Netscape - that was anti competitive for some but having lived through Netscape 4.x I can assure you that Netscape's incompetence was also a big part of their failure.
You and others (given the down votes) may not agree with the narrative and don't want to hear it, but it is a probable argument that can be used to go after Google and stay any effort to allow them free use of other companies patents. The original DoJ's case against Microsoft attacking IE was rather out there given Microsoft's other behavior (i.e. no matter what OS you buy Microsoft still gets its fee).
// I think this is my last comment on any Google story. Companies can do cool stuff and still do uncool things, just like people. Every company tries to protect its revenue stream in whatever way it thinks up.
