Honestly...
I am a huge advocate of light, convertible, tablet/netbook type Android devices. For me, the ability to take something as powerful as the Transformer that is also as lightweight and long-running with me on travel has been a tremendous gain. These devices are very liberating in a way that a traditional OS based device simply can't approach. BUT... if you want a full fledged Office Experience, I don't think there is anything currently available that is likely to actually satisfy you. I hate to say that, but it is probably the truth. I'd find a friend with a Transformer or Acer Iconia and sit down with it and try one of the apps suggested here and see what you think of it... because maybe I'm just being too critical. Honestly though, my gut feeling is that for an Office power user, the Android and iOS alternatives just aren't completely there yet, if they ever will be.
