When I read such articles, that's when you realise that people are resistant to change. It's like those people still using Windows XP because it's the best. Tech is in constant change, but at some point, some people just give up and decide not to join in anymore: not to make facebook accounts, not to join twitter, not to upgrade their OS, not to switch browser.
That's what this post is: someone refusing to face the changing landscape of tech.
Mobile is greater than what it seemed to be at the start. Mobile operating systems are no longer button phones, they are computers, and they are going to integrate with the desktop tightly. That's the new world, and in such a world, there are only going to be just a few platforms.
Nokia had almost zero chance of being the new platform. Microsoft continues to maintain strong platform presence on the desktop, browser, gaming console/set-top, and they have brought in a strong mobile platform, even if sales are lack-luster now.
Android provides a free, single platform for everybody else.
Apple has their iPhone eco-system, which is not open to others to use.
If Nokia stays on their platform, they will surely fade into irrelevance, and at some point they will need to switch to Android, and be years behind all the other Android clones. That would be the end of Nokia.
The Microsoft-Nokia deal basically has given the Microsoft mobile platform relevance, and it means that a big chunk of the mobile market will be MS/Nokia, and that will ensure that Nokia remains relevant.
With this move, the integrated platform market has basically been divided into three equal chunks (Android, iOS, MS) and for the new few year people are going to have to choose between those. Nokia as a hardware manufacturer - if it does good deals with MS, will basically form one-half of the third major platform. That's how it will stay relevant.
After this deal, Android is likely going to become more popular, because most other hardware manufacturers will bet full-scale on android. However, the problem is that Android lacks a desktop environment, so canot be as tightly integrated as the other two platforms could.
So I expect Android to take the role of feature-phones now, while MS and Apple control and split the high-end market.
I'm not sure what role blackberry will play in all this.
