Indian Users Slowing Moving to Facebook!

If you check recent trends.... orkut users of India are gradually moving to facebook. facebook is going to be face of India's social networking. ( i am not considering twitter , and other Indian SNSs like zapak, bigadda, ibibo, indyarocks etc)Why ? I asked myself and my friends and find out following points in favor of facebook:

1. Facebook has differential approach to pc users, mobile users, sms users (specially for 3rd world countries), different mobile handset users (specific handset settings like iPhone)
2. community of orkut can be accessed via m.orkut.com while m.facebook.com is more advanced
3. as fb offers devilery of sms updates to most of Indian carriers it gains more popularity than orkut.
4. new orkut theme - that sucks completely/
6. people get bored with orkut.
