The Motorola Xoom, like the iPad, is mostly dead air and a battery. iFixIt did their best to tear out all the important bits, finding a large screen, a handsome circuit board, and what appears to be a dead PCI board dedicated to future upgrades.

The chips they found include:

Broadcom BCM4329 802.11n Wi-Fi, Bluetooth 2.1, and FM Tuner. There’s also a Broadcom BCM4750 Single-Chip AGPS (located nearest the top right corner).
Hynix H8BCSOQG0MMR 2-chip memory MCP
AKM 8975 Electronic Compass
Qualcomm MDM6600 supporting HSPA+ speeds of up to 14.4 Mbps
Nvidia Tegra T2 dual-core ARM Cortex-A9 CPU and ultra-low power GeForce GPU.
Texas Instruments 54331 Step Down SWIFT DC/DC Converter with Eco-Mode
Samsung K4P4G154EC DRAM

It’s interesting that Motorola thought to offer upgrade slots for this device. This points to a more modular approach to hardware design of tablets, a great improvement over the “closed” nature of earlier tablets. Here’s hoping that some day we will be able to swap out memory and storage the same way you’d do it in a laptop.
