I don't find honeycomb to be that buggy. iOS has its share of bugs crashes etc depending on the apps you run. I think in a week I've had one crash on Honeycomb.
As far as the Xoom being unfinished true but both features 4g and flash they are going to add are not even going to be available on ipad2. So the bloggers etc that keep hammering that probably work for Apple.
I find Honeycomb smooth and more elegant than iOS. So I just don't get the half baked statements of many of the blog sites. For the record I switched from ipad to Xoom and still have an iphone 4.
