Well its a fact the Apple makes more net profit per phone, than some co's make in gross profit on Android. Apple sells more than their phone, but the name, that they've spent billions marketing.
On the BB issue, unlimted data isnt BB's only trump card, it's still their email service and BBM nad flexibility. My BBM is still far better for emailing than my iPhone. The stupid iphone won't even let you upload multiple attachments without having to download a program for it, and take ages to send a simple email.
Apple is just an inflexible phone, period. If they released a phone for the youth, IT WOULD NEVER SELL in current form. The youth Bluetooth each other songs, and download them from the net straight to their phones. Can you do that with an idevice? Hell no!! Those are some of the things that keep people away from Apple, and the reason why I wont buy another iPhone again.
BBM is still RIM's biggest trump card, I wish they would realise this. WhatsApp is BULL, period. As much as Apple users like to attach prestige to having their iPhones, so do BB users with regards to BBM. A BBM pin has become more than that, it's almost like an identity. Personally, I ignore WhatsApp and SMS's. If you dont have a Blackberry, then rather call me, as I really regards SMS as ancient, and WhatsApp an outright joke. I have 200 BBM contacts. Much like me, they've all kept their BB's and use them as a mistress, rather than a main phone. If BB could capitalise on BBM, then they'll have one thing other co's like Nokia didnt, a continued relevance in people's lives.
That could possibly be they're saving grace. People have not forgotten and put away they BB's like they did Nokia. How ever small the role may be, BB has still got relevance in many people's lives, which can pave the way for a great come back for them.
