London (CNN) -- It's easy to ask why Microsoft would want to buy Nokia when its share of the smartphone handset market is sliding. What can Microsoft possibly do to reverse Nokia's fading fortunes?
The emails from analysts pouring into my inbox are evenly split -- great idea or a disaster; relatively cheap bet by Microsoft (at $7 billion) or a share price-eroding move.
So, can Microsoft leverage its monopoly selling software and services contracts to corporations, and get a slice of the employees' mobile business? Or, by getting a product which it is already in partnership with, is Microsoft simply buying the cow when it's already getting the milk?
The deal comes as no surprise. When Stephen Elop left Microsoft more than two years ago to become Nokia's first non-Finnish CEO, it seemed logical the two companies would eventually meld.
One question rightly being asked, is whether rival handset makers or operators will simply stop making phones with Microsoft's mobile operating system.
In my view, it doesn't matter. Nokia and Microsoft joined ranks two years ago and the others were a fraction of Microsoft's fraction of the mobile operating market.
The question in my mind, is whether Microsoft can take its mobile operating system and make it a player in the burgeoning market of cheap smartphones.
Nokia still makes more handsets than any other manufacturer, and now that's Microsoft's business. Nokia's market share was 23.4% in the last quarter of 2012, according to research firm Gartner. That's because Nokia sells an enormous number of cheaper mobiles in emerging markets.
Microsoft's task, then, is to stuff a cheaper version of its smartphone OS into these more affordable phones. The sales channel is there. The brand name of Nokia is known the world over. Microsoft is an expert at sales and marketing.
The bigger task may be to integrate more than 30,000 employees into the Microsoft ecosystem. Many companies gamble that a bolt-on acquisition is the sure-fire solution to a missing piece of the puzzle. But it can set a company up to fail.
A real competitor to Google-Android and the Apple iPhone could be around the corner. But it will be a huge task for Steve Ballmer's successor.
