Why Blackberry is so damn expensive??

I always wondered why in the world does Blackberry is some damn expensive and why does it always come with local operators contract? Which meas that when you bought your blackberry from Maxis, you can't use it with ur Celcom simcard as it will not work as the device had been locked by the local operators and of course you can still unlock it from the service centres that are offering this service for a very cheap price around KL..

So back to the question again? Why does blackberry is so expensive compared to other mobile phones even though its specifications are not so up-to-date.The main reason is because of the BIS (Blackberry Internet Service) which is a 24/7 service that offered update on every email,sms,or even your social networks updates you can get it on the go without a fuss as you are connecting to the BIS 24/7.Thats also why Blackberry only provided to the local operators as it required unlimited data plan to allow BIS to work.

So,next time time when you want to buy a Blackberry,think again is it worth it?
