In the video Motley Fool senior technology analyst Eric Bleeker looks at what lies ahead for Nokia (NYSE:NOK) in 2013. He pulls out a few data points that any Nokia investor should keep in mind at all times.

Last year wasn't a great one for the Finnish phone maker. Sales of Symbian smartphones dropped drastically, from 93 million units in 2011 to 26 million. Moving to Windows Phone has been little consolation, since the company sold only 11 million Windows Phones, taking total smartphone sales to just 37 million.

On the other hand, Microsoft (NASDAQ:MSFT), with its $66 billion cash pile, will provide a solid boost for Nokia in 2013 and won't hesitate to spend money on promotions to make Windows Phone relevant. That's how Samsung has become such a success. Samsung not only has a large ad budget, but a sales promotion budget four times of that of Apple (NASDAQ:AAPL)

Finally, Eric ends the video with a word of caution for Nokia investors. Many companies in similar situations to Nokia either ended up being acquired or went bankrupt. Though Nokia has Microsoft to back it up, investors need to be alert.
