Re: 520, 720 & 920
Those are Nokia Lumia phone models. And the "little group" has only one OS version, Windows Phone 8.
I find a bit strange to see all the Nokia and Windows hate on this forum and the obvious anti-Microsoft bias of the authors (but I can't fault them for giving their readers what they want).
This is strange because Windows Phone has a larger market share in UK than in US (6.7% vs 4.1%), and I don't see such anti-MS/anti-Nokia articles on US tech sites. BTW, of those 6.7%, 5.6% are Nokia Lumia phones.
Also, the doubling of market share in one year (from 3.0% to 6.7% in UK), is hardly a reason to post tasteless stuff like "Smell of death putting them off, perhaps".
Yes, Nokia makes mistakes, one of them being not releasing the phones fast enough (in some countries the high-end models arrive about 6 months after the initial launch).
Yes, Microsoft makes mistakes, like not allowing the first generation devices to be upgraded to Windows 8.
But even with all those mistakes, the growth in market share is healthy. If the trend continues, by the end of this year Microsoft and Nokia could secure third place for smartphone OS and as a phone manufacturer. The other manufacturers, except Samsung and Apple, are only a few percent in front of Nokia, and dropping.
I'm a HTC Radar owner, and I will switch to a Lumia 920 at the end of my contract.
