Xoom Review at Ars Technica

"Although the Xoom has a lot to offer, the product feels very incomplete. A surprising number of promised hardware and software features are not functional at launch and will have to be enabled in future updates. The Xoom's quality is also diminished by some of the early technical issues and limitations that we encountered in Honeycomb. Google's nascent tablet software has a ton of potential, but it also has some feature gaps and rough edges that reflect its lack of maturity."

This is a very in depth review just as you would expect from Ars.  If you're considering buying the Xoom you should definitely check out this review first to get a better idea if it really is the tablet for you.  While many great features are pointed out there are also a lot of warning signs brought up.
