Of course, a lot of what Microsoft has been putting into Windows over the last year has been expressly for larger screens, think Surface Pro, Surface Laptop and compatibles, though I can't help but wish that Edge had had more development for Windows 10 Mobile before the branch freeze at 'feature2_rs3'.

In other news, a week today is 'Patch Tuesday' and we're expecting new builds and fixes for all Windows 10 Mobile phones on Creators Update (Redstone 2) or Fall Creators Update (Redstone 3) - this is the vast majority of smartphones used by AAWP readers, so I'll certainly cover that in detail.
