Please, enlighten me.
I live in the real world, where 15+ years ago, you HAD to get a PC. Getting anything else was sad. Today, getting a PC is sad, and you HAVE to get a MacBook.
MS is still a very strong empire because they're so deeply entrenched across the globe with their crappy OS. Time solves this. Their technology and innovations now are crap, and the market just needs to catch up to their lack of innovation. Give it 10 years.
Microsoft offers more than just Windows and Office. They have a very VERY large enterprise level of software and support, from Database back-ends, Data entry systems, Accounting packages and modules, data systems, analytics, reporting services.
They also on top of that offer Services for enterprises. server platforms, Internet Information services
Windows is their most known product. But it's by far not their only thing. Their front consumer face of Windows, Xbox and a few smaller players in the market like the WinPhone and handhelds is only a tiny segment of what they actually have and do.
Are they the only option? no. There are a lot, some do things better, some do things worse, But it's the way that they support, those products which is unrivalled currently in the market.
If all you've ever seen is what desktop users have and argue between Mac and PC, you are only seeing the tip of the iceberg. And we all know that Icebergs above water portion is tiny compared to what you can't see underwater.
I'm not going to ever say that 10 years from now Microsoft will be the #1 player still. That could change Tomorrow for all we know.
But as long as Microsoft Continues with their current offerings, there isn't much in the way of offerings out there right now.
