After testing the Xoom for about a week, Mossberg goes so far as to say that the Xoom beats the first-generation iPad "in certain respects." For one, Mossberg believes the Xoom has a more "potent" processor than the current iPad, along with better speakers; and higher screen resolution. Whether the Xoom can compete with the next version of Apple's iPad, which is expected to debut next week, remains to be seen. Either way, it seems clear to Mossberg that Apple's monopoly on the tablet market is coming to an end.
