Well, I'm not necessarily any smarter than you, but I wonder if it's because the tablet is 1920x1080. I think this it (or maybe there's one more) at that resolution. It's quite possibly the Netflix app that's to blame, not able to adequately address that resolution. This may be a "wait and see" sort of thing, but if Asus wants to move these things, they should make darned sure that the developers are writing apps that support that resolution. I'd be willing to bet that's the major issue here with anything not running buttery smooth - it may not be the hardware but may be the software. Still, how can you know right now?
iPad has the advantage of the "you vill program it dis vay!" from Apple. I think Android is still weak there, but I'm willing to put up with it as they catch up.
