Just watched new features of Windows Phone 8.1. It has tremendous improvements over previous versions.
1. It is free for hardware manufactures, thus bringing phone cost lower than android ones
2. Android is a malware. As recently quoted by sundar Pichai android is not made for security. Windows will give a sense of security
3. Windows phone OS is very stable
4. Cortana the personal assistant, an awesome must have feature.
5. As Windows OS holds a large 80%-90% of desktop user base. Windows phone will be lot more intutive.
