Analysts say Motorola's Xoom tablet computer is powerful enough to challenge Apple Inc.'s iPad.

Motorola Mobility Inc.'s gadget went on sale Thursday. It's seen as the iPad's first real competition — it has a bigger screen, cameras for video chatting and recording high-definition video, and it runs a new version of Google Inc.'s Android software.

IHS iSuppli peeked inside the Xoom and found that Motorola picked a lower-end screen than the iPad's, but parts that control its touch-sensitivity are on par with Apple's product.

And, the processor that controls how fast software runs is twice as speedy as Apple's own chip.

Xoom, which costs $600 with a two-year contract, can be upgraded for a faster Verizon Wireless network later. ISuppli found that people will need new hardware installed for that to work.
