Say, whatever happened to Nokia? Oh yeah, Microsoft destroyed it through legendary levels of sheer ineptitude.
Sadly, Nokia was already rotting from the inside out before Microsoft bought it out. While it had awesome engineering resources producing its enormous lineup of products, and a superb manufacturing pipeline, I don't think its management ever really came to grips with running such an enormous business once it became a global powerhouse.
There were a lot of different projects going on in parallel, without clear central guidance to control everything. For example, the classic OS Nokia used on its most popular smartphones was Symbian; but, this OS really didn't scale up very well, and the research department decided to look for alternatives. They came up with Maemo in 2005; this OS was, in effect, a full-blown desktop Linux OS, with a UI designed for portable devices. Note that they released the first Maemo device
years before the iPhone came out.
However, management couldn't decide whether to stick with the OS that was their bread and butter (Symbian) or push hard for the new OS (Maemo). So, they just punted and tried to support both at the same time.
Then, the iPhone came out, and blew everyone away. Including Nokia's management. They quickly decided that they needed to compete with the iPhone, and ordered their research department to stop what it was doing with Maemo and create an iPhone-like device. Which they did; they changed Maemo until it looked very much like iOS (removing many of the features that made it unique), placed it onto a phone that looked like an iPhone (removing many of the features unique to Maemo phones), and finally released a device that was similar, but in every aspect inferior, to an iPhone.
But even that didn't matter. The management was ripping itself apart by now, and so they brought in a new CEO, Stephen Elop. Who had previously been an executive at Microsoft. And he had a plan -- he would axe the entire software development staff at Nokia, and switch all their devices over to using Microsoft Phone for their OS. The entire Maemo development team was being shown the door before the first Nokia iPhone clone was sold.
And, of course, Elop ran Nokia straight into the ground. Windows Phone was not ready for prime time, the remaining Nokia staff couldn't maintain their other operating systems, the company hemorrhaged cash, and finally Microsoft was able to swoop in and buy it for a song...
Anyway, tl;dr: Microsoft did not destroy Nokia. Nokia committed suicide.
