"Google refused to give out any information about Honeycomb, and the end result was no one could deviate from the reference design," said a senior engineer with a large mobile systems maker in Taiwan.
"Android 3.0, Honeycomb, was designed from the ground up for devices with larger screen sizes and improves on Android favorites such as widgets, multi-tasking, browsing, notifications and customization," said a Google spokesman.

"We’re committed to providing Android as an open platform across many device types and will publish the source as soon as it’s ready," he added.
Google was quick to jump on the tablet phenomenon with Honeycomb, enabling Motorola to release a tablet in less than a year after Apple defined the new market with its original iPad. However, it is clearly struggling to find the balance of how to enable a broad industry of mobile systems makers without losing control of the quality of its code and the systems that use it.
At an Android developer conference earlier this month, two Google developers showed Honeycomb running on the Motorola Xoom tablet released in February. At that time they said Google had not decided when it would release the source code for Honeycomb, and they said Google plans to release a separate version of the code optimized for smartphones.
"Honeycomb is all about the tablet, but along the way we made a lot of general improvements in the user interface," said Chet Haase, a Google UI developer who showed the software to an audience of more than 400 at the conference in San Mateo, Calif.
Acer, Dell, HTC and Samsung are expected to roll out tablets using Honeycomb soon. Some systems
