Oh, please no. Why would you want floating windows on a tablet? Can you really envision yourself dragging several windows at a time on a small 10" screen, or even smaller than that? Not to mention the kind of battery and CPU drain that would be.

If the perception that "Android is a battery hog" because of widgets and having a more "real" multi-tasking system, hasn't negatively impacted Android yet, this certainly will. At most Android tablets just need a split-screen view.

I agree. Floating windows would be horrible on tablets. I don't think this Samsung implementation is great for usability either.

Microsoft is at least heading in the right direction since Windows 8 allows two programs metro apps to run side-by-side. Unfortunately, even their implementation has flaws: it only allows fixed sizes of 70%/30% or 30%/70%. Users can't manually adjust the divider between the apps to 50%/50%.
