Dear Arpenteurdetoile,
You are totally right. I am an Android user myself, for a long time and got used to the system. Last time I changed my phone, the WP platform was really lacking in term of applications ... that I use : my Bank had nothing for WP, my ISP had no apps for using the free wifis, program the STB to record remotely, etc...
But that was more than a year ago. If I look now, I see that 95% of what I use is there and the only thing holding me back to switch my Android for a WP phone is that I don't consider my Android phone is not enough depreciated yet. The few percents of missing applications are an acceptable tradeoff to step into a lean system that offers better battery life and a streamlined interface. I always liked the customization possibilities of Android, the alternative ROMS etc... but after some time, you just become bored of all this mess and the time you spend updating, testing, troubleshooting. I've come to a moment when all I want is a phone that just works efficiently and reliably for me, and that's exactly what Nokia/WP models are achieving !
