I dose have a Z10 that is working perfectly. Smooth OS, easy to use gestures, perfect business features.
Just bought a Z30 for my wife, she is enthusiast for the beautiful screen, easy learning curve and nice features. She never have used any BB before, just iOS.
I installed a couple of needed Android apps, from 10.2.1 you can do it just downloading the apk.
Good to have a easy to use App Store for Android, anyway I don't feel so much the need of it.
