The new Windows 10 ecosystem is now more consistent than ever. The only drawback is the lack of apps and slowness of them in some circumstances. The only area I feel as a personal opinion that Windows 10 excels is in Calendar; email and Office apps. So far as 3rd party apps are concerned there is some way to go to offer that speedy app launch that you get with some Android apps. Just to say compared with how Windows 10 mobile started out and the updates that have brought extensive optimization Microsoft has a chance to regain Market share.
