Huh... Maybe we have different levels of lag we can accept. Every Android tablet I've ever used was not nearly as snappy as an iPad. It's hard to imagine that ALL of them were bloated to death. I never experienced that with Android phones (in-store being slower than at-home) so I really don't see how it'd be that different with tablets. Maybe I'm too picky, idk.
I owned the Xoom a while and now a Tab. It does have its quirks. Depending on what keyboard you use or Live Wallpaper it can get a bit finnicky. Its the price you pay for having more freedom and customizability.
