You cant compare Windows Phone and Android devices... is totally different... Windows Phone OS is very stable and safe (no viruses or malware) but not have visual or any customization as Android OS... also for some Android users is very difficult to switch to WP if expected to be all the same as on android... for my PoV, WP is much better than android and i love it. if you not see how WP works, try see online demo http://try.nokia.com/#en-GB
