I knew they wouldn't because of Steve Jobs enormously jealous ego. Just like he has gone out of his way to lie and declare war on Adobe and Flash, he's not about to incorporate highly useful widgets because Android does. It's really a shame his childish side, prevents us from getting the best of all worlds in what could easily be an iPhone even more fantastic that the any before it.
At the end of the day there are many limitations that are easily removed, but Jobs would rather act like the Dictator he is, than to borrow good ideas that are well liked items which ad fun, speed, and efficiency to his products.
But then again, that said the hypocrisy of Apple and Jobs is that they indeed do copy many of the features in several of their new products.
You simply cannot count on Apple anymore. Their reasoning and decision making is very arbitrary.
Every top of the line laptop in the PC space has had 3G connectivity built in for years, and yet the MacBook Pro still suffers from a lack of it. When I can buy a very good, robust, durable and fast ThinkPad in the same configuration for half the price. That laptop comes standard with every form of connectivity one could want.
I could go on and on giving example after example as I'm a huge Apple enthusiast and computer user that works in a cross platform environment. Therefore I always have the latest laptop from each manufacturer. While my personal preference is Mac, it's not because they are cutting edge, or feature all the options one would need, but rather because I've been using them so long as my personal machine and have a huge selection of Mac Gear.
Cheers...
