Which Android tablet was the first to run Android 3.0 Honeycomb?

The Motorola Xoom was the first Android tablet to run Android 3.0 Honeycomb.

Motorola introduced the Xoom at CES 2011, and its first version went on sale in February 2011. It launched with Android 3.0 Honeycomb, Google’s first Android release designed specifically for tablets. The Android 3.0 SDK became available on February 22, followed by the Xoom’s commercial release on February 24.

Honeycomb redesigned Android for larger displays. It introduced a tablet-oriented interface with an on-screen system bar, software navigation buttons, a redesigned action bar, improved multitasking, richer widgets, and a two-pane layout in apps such as Email and Contacts. These changes helped Android compete more directly with the iPad-era tablet market.

The Xoom is sometimes described simply as the first Honeycomb tablet, which is the clearest formulation. Other tablets, including models from Samsung, Acer, and Asus, followed later with Honeycomb or received it through updates. Honeycomb was eventually folded into the unified phone-and-tablet Android 4.0 Ice Cream Sandwich release.
