The same reason people have started adopting micro-sim. Apple is one of the very few people that use it but yes it out there and it hasn't bothered people but i am sure that little bit of space made a difference in making of the iPhone 4.
In order to move forward in one aspect you need to sacrifice another aspect. I am not saying apple's need for a smaller sim is justified, but i not saying its not justified either. All i am saying is don't judge until you see the final product. Stop being so angry about everything.
You don't know the reason for the smaller sim, it dosent have to mean thinner phone. For all your know it could be some revolutionary breakthrough in which helps the next iPhone achiever 10 times more battery power
With the revolution in interface it made way for the design to be implemented more easily. I dont remember seeing any design similar to the iphone on the mainstream before the iPhone do you?
Its funny how people are hating on this smaller card because they think the iphone is gonna become smaller but are fine with a soft sim card?
I know we would all rather have soft sim card's but that means it gives apple the chance to make the phones even smaller?
Touch screen phones with no keyboards? Er yeap they were out before the iPhone mate, and they had more features too. The soft sim was slated by the industry and the network providers hence Apple were not allowed to implement it, and there is no tech they can come up with to warrant smaller sim card as the space saving is minimal.
I like having volume buttons and on he very thin phones reviewers have already slated the button sizes on the side.
Apple should just leave well alone. And as for innovation, well it seems plenty of other manufacturers are coping pretty well in that department without forcing an entire industry to adopt a new standard for their selfish gains.
And a LOT of people would rather not have soft sims, because they like to change phones every year and it would be an additional pain to use. Most likely why the network operators said no.
