I'm convinced that the reason is some slightly incompatible program. We have three XOOMs in the family, all upgraded, and we have been very aware from the beginning of loading and testing programs.
We only load one app at a time and then run the tablet through it's paces. One force close and the last app is removed. We have everything we want, just many of the apps aren't the ones we were used to on our phones.
The thing that wasn't clearly communicated was how much of a "work in progress" Honeycomb was/is. If a user was aware of this, they would have a great experience, like we have had.
As for going to get an iPad2, I always say if you don't want to think, don't need the flexibility and superior utility of an Android device, go for an Apple. I was an iPhone guy for the first three iterations and checked out the iPad when it came out. Unfortunately, I'm an enterprise user and iOS was woefully inadequate for me, so now I'm on Android and have reduced my usage of a notebook by about 85%. I've been told Apple is getting better at the enterprise thing. Not sure where, as I'm no longer involved with them. Still no folder navigation, which is a non-starter, but I'm told they are getting better.
