Samsung multitasking. Wish BB10 had it

5:06 onwards. Damn, that's pretty advanced. Honestly wished BlackBerry had those abilities, even without the pen. I would love to be able to drag and drop pictures off of websites into BBM etc without having to hold down the image, select share, select BBM, select contact and then hit send. Like that's true multitasking, not BlackBerry's attempt. No wonder Samsung is the leader in the phone market.
Almost makes me wish I had a Note 3, except it's Android.
