I had the opposite situation. I went from a Nexus 4 to a 925 and back to my Nexus. What I found in my experience is that you grow accustomed to a certain feature or features, and when you cant find a satisfactory solution in your new device it becomes a hindrance. These hindrances lead to a degraded experience and ultimately make you unhappy with your device.
For me a normal day with my device is this
Check traffic before work. Google now is excellent at showing real time traffic as well as how many minutes it will take me to get to work. This all shows up right on my home screen. Drive Commute does an ok job at this but it only shows commutes to and from work. Google Now shows me traffic and time back home no matter where I am.
Stream Google Music All Access on the way to work. There is no Windows Phone app that gives as good of an experience on WP8 as its iOS or Android counterparts do. This is unfortunate
Texts, emails, web browsing throughout the day. All of these were equal on both platforms
Reddit and Instagram. Baconit is an excellent app Instance was the best Instagram app I found but it was lacking features
Stream on the way home
My weekends consist of using the explore feature in maps to find activities of interest and then navigate to them, streaming, taking pics web browsing, and texts.
Now my hindrances were more app related than device related and what I learned was that i was way too dependent on apps to make WP8 my daily driver. As much as I loved the 925 camera and Here Drive at the end of the day, the most important things to me fell short. I went back to my Nexus and bought a 521 as a secondary device. While the 521 is a huge step down from the 925 I got the 2 important things to me. I got Here Drive back and the camera button. I love taking pics with the Nokia, and the 521 does an adequate job for me.
For what its worth you can do things to make your One mimic some of WP8
Launcher- Launcher 8 will give you the tiles back. Bonus the phone and sms tiles update when you have a missed call or text

Keyboard- Swiftkey Very good word prediction and a lot of custom options

Without knowing your business needs I cant offer alternatives to accomplish what you may be looking for (and there may be no way to do it ultimately) but you should check out Android Central, there is a lot of good info and helpful people over there. They may be able to help you accomplish what you would like to do, or at least make it bearable until you sell the One and buy another Lumia
Good luck :smile:
