Windows 10
Its not looking good for Windows Phone.
Microsoft are going to struggle to get Operators/Carriers on board to offer customised updates to Windows 10 on Nokia mobile devices, that incorporate the new combined Windows Phone/Windows RT OS.
That sort of support and investment only happens by operators when they have sold a few million of a mid/high end device, with good margins. Disinterested Operators have sold a small bucket full, equivalent of a flee market sale, in terms of the overall mobile market, of mostly low end Nokia Window Phone and margins are tight.
Microsoft need to start confirming which devices will support Windows 10, through their own measures, which are getting ditched, in the case of Windows RT. Otherwise a sales vacuum will ensue, this Christmas.
With the 4G Samsung Galaxy S4 Mini now £119 PAYASYOUGO at Three, Samsung/Android is coming in for the kill. Microsoft Lumia 535 are now having to compete with Samsung, when it was once cheap Chinese Androids.
