Lot of talk from folks with little to no experience with the technology. I have both a Xoom and an iPad2...purchased by my employer because of my line of work. I've switched to the Xoom, because I'm a gadget junkie. Simple fact is Honeycomb and many Android apps are very, very, very rough right now (force closes, crashes, etc). Anyone who tells you differently is full of it. But I remember early iOS versions being less than ideal too. Honeycomb is a baby compared to iOS.
I believe Honeycomb has lots of potential and I think I will ultimately prefer it to iOS. I can live with it's rough edges because I'm a tech junkie. But in almost every case when I'm asked to recommend a tablet I still say iPad2. Not only because iOS is much more polished, but (despite raw numbers) there are sooooo many more polished, usable tablet apps in the iTunes store.
Bottom line, iOS/iPad today, but if you underestimate Google moving forward you would be quite unwise.
