The specific comment was that the browser force closes "a lot". By a lot, I understood that to be more than once or twice a day, which is what I've personally observed. A lot to me is once or twice per hour. That's what I said was full of crap.
Reviewers are human beings with opinions like you and me. It reminds me of the "reviewers" that trash every Chuck Norris, Sylvester Stallone, or Arnold Schwarzenegger movie. It is very difficult for reviewers, especially in the technical area, to suppress their bias. That doesn't mean their reviews are ALL crap

, but it means you should not consider them the be all end all. If Ars Technica says so, I also like to hear from other sources, including actual owners, and preferably I like to experience it myself (which is why I bought one and am keeping it, mostly to play with it, learn, and have fun).
I get no compensation from Google or Motorola for "defending" the Xoom. It just irks me a bit having experienced the Xoom myself firsthand to see some of the bias and outright misinformation some reviewers and techno heads are putting out there. It worries me that when I can't afford to experience a new gadget myself and need to reply on their advice they are going to steer me wrong.
YMMV.
