"Look like" is the operative phrase. Hardware specs do not a successful tablet make.
Yes, Xoom has more hardware features. But try using one side by side with an iPad 2 and you quickly realize that you you don't use hardware , you use software, you use an OS, you use an ergonomic design. A widescreen display is better for HD video, but not as good for almost everything else you do on a tablet -- and it makes the thing more awkward to hold and use in one hand. An SD card reader is something that seems useful to have, until you realize that it's possible to design an entire OS that makes removable storage moot. More RAM sounds like a good idea until you realize that what you need is "enough RAM" combined with an OS designed to optimize its use.
Android tablets generally suffer from the same inefficiencies as Windows PCs: the hardware has to be designed to run code that hasn't been optimized for that hardware, and so brute force is required to compensate. Apple's approach, integrating OS and hardware design while carefully vetting all applications to assure they won't break the system, seems overly restrictive to some, but it results in a trouble-free and very elegant user experience. Which IMO is what makes a "better" tablet.
