Good thing, for the 'real' Nokia
Something many punters fail to notice is that Nokia is one of the top three mobile network equipment manufacturers, along with Ericsson (Huawei being the third), who incidentally off-loaded the last remains of its handset business to Sony, just the other year.
That was really a good thing for everyone involved, since Ericsson never understood consumer electronics (which is why they kept making phones for grey-suited middle-managers at Volvo while Nokia took the world by storm with snap-on covers). Of course, Ericsson never made any serious profit from its handsets, even before they were crushed by Nokia. It was always, first and foremost, a networks company.
Now that Nokia's handset business has failed, for reasons explained and speculated upon all over the tech press, it is doing the the exact same thing. Except, unlike Sony, Microsoft has about as good an understanding of consumer electronics as Ericsson ever had, which might not bode so well for the former Nokia employees that transfer, but will make for entertaining reading in the tech press over the months and years to come.
Nokia, on the other hand, will continue to be an important and profitable mobile network equipment manufacturer.
