Microsoft has done it twice already. Once when they left Windows Phone 7.5 devices user high and dry and didn’t offer them upgrade path to Windows Phone 8. And now with leaving Lumia X20 device users out of Windows 10 Mobile upgrade cycle when most of the devices have been able to run Windows 10 Mobile‘s badly broken Alpha and Beta versions successfully for more than one year.

So, take the poll and do let us know what you think about prospects of Lumia X30 devices going forward. Will Microsoft use these devices as Guinea Pigs and will refuse to upgrade when Redstone hits.
