so you are planning to spend 30K on a
smartphone.
i would suggest waiting for nexus prime launch tomorrow and see what it is priced at in the coming weeks.
blackberry devices are great but you have to realize that there is a fixed monthly cost that is usually higher than 98 bucks we pay for airtel and vodafone edge.
battery life should be great on blackberry but the app experience would suck. it makes for a good purchase if you have friends who are using it. otherwise, i would suggest sticking with
Android or horrors, get an
iPhone 4 (if 4S is priced atrociously in India).
blackberry platform is expected to see a major transformation next year with the launch of their QNX mobile platform that would replace Blackberry OS. QNX is used on their Playbook and this is expected to be a mobile OS fully optimized for touchscreens.
Blackberry OS 7 is still a transitional operating system.

meego of course is dead on arrival. n9 is priced too high in the international market. it is not clear if it would be released in india officially. imported devices would be shit expensive.
that reminds me, you should also look at
windows phone devices. they are actually decently priced and unlike android phones, they do not suffer from performance issues generally.
