I liked it and I had many Windows Mobile Phones. App support was always the biggest issue and with WM10 the OS also was not stable enough (Wifi crashed regularly for example).

If they were to relaunch Windows Mobile they would need to make all Android apps runnable from the beginning. Otherwise, there is no chance to survive and gain marketshare. It's possible on Windows 11 with the Linux Subsystem now. But I don't know how much work it is to bring that on a phone.

Would be cool but it's very unlikely :(
