Windows Phone 10 apps seem less convenient than in Windows Phone 7. Some of the gestures gone, hamburger menus instead... And why are the app menu buttons on top instead of bottom? I understand that they want to have the same codebase on all three screen sizes, but simple 'responsive' approach is not perfect. The WP10 platforms needs to make the best of its advantages, not become the second android mess where every app has different UX philosophy. MS should provide gudelines for tailoring apps to WP, but srsly atm they need to fix these office apps before releasing them.
