i think it looks pretty nice. not sure how i like long swips. could be too long and too slow on a tablet. buttons might be faster but we will see. swips on nexus 7 is pretty slow (becouse of size) compared to buttons.

true nultitasking requrires multi windows so that the device isnt slowuing down the user. split screen fearure might be a nice first step to multiwindows. looking forward to that feature.
