I heard that MS office,onenote,calender,and outlook mail app all there are available for free on iOS and Androids.I haven't used these on any other OSes yet.I can't really believe MS is giving away these wonderful services for other OSes. is there any catch or trade-off with Android versions of these services? or they are as same as on WPs?(I heard they are better than WP's) .Other than the unique UI of WPs, all these great services are not only like a heart of wps but also a major selling point for wps.Just for these services only i bought a wp.If MS made all these apps available free for other Mobile OSes then what's so special about WPs? there is no reason for me to still use wp is there?.In my opinion they shouldn't give these apps at all to other OSes if they really want to boost the market share of WPs and maintain it's uniqueness.Please help me take my decision.Now I am planing to switch to android.Will I miss any of these services if I switch?
